Reducing Virtual Simulation Study Time

SHELL BLOG 3

Using SOLIDWORKS Simulation to optimize designs is a cost & time-saving practice, but generating those studies can sometimes be time consuming. When creating a simulation study one of the first steps is to take our SOLIDWORKS solid model and turn it into a mesh model. This process of meshing is also known as “discretization”.

When running a SOLIDWORKS SIMULATION study and creating a meshed solid model, this mesh is made up of many solid ELEMENTS. These solid elements are 4 sided, with each side taking the shape of a triangle. Each edge of the solid element contains a NODE at both ends and a NODE at the midpoint for a total of 10 NODES per element.

An important concept to recognize when working with SOLIDWORKS SIMULATION is that each of these nodes represents the unknown variable of an equation. In linear static stress analysis we are typically running a study to determine the stress imposed on a model. This stress is derivative of strain, which is a derivative of DISPLACEMENT. Therefore, each node of a solid element represents the unknown variable of displacement, which we are solving for when we run our SOLIDWORKS Simulation Study.

If we apply a force to the lower face of this model and mesh using solid elements, we can see that the maximum stress is 83.349 MPa, and that the maximum displacement is 2.112 mm.

We can also see that the total number of nodes used to solve this study was 80052

Since a single node represents an unknown variable for displacement, and we are solving equations for displacement, it stands to reason that less nodes in a study will result in a shorter time to calculate our results. While there are several techniques to reduce the amount of mesh in a model, one technique is known as a SHELL MESH.

 

A shell mesh differs from a solid mesh in that the elements are 2 dimensional rather than 3 dimensional. A shell mesh element is a single triangular face with nodes at each corner and at each midpoint, for a total of 6 nodes per element.

Some models are good candidates for utilizing shell elements. Some are not. The most important qualifier in deciding to use a shell element mesh is the material thickness being uniform. If the material wall thickness is NOT uniform, the model is NOT a good candidate for a shell element mesh.

 

In the example of the bracket we are using, the wall thickness IS uniform so this IS a good candidate for shell meshing. In order to turn a model with uniform wall thickness into a shell element mesh, we must first create a surface model, in this case using the mid-plane option. Once this surface model is generated, we are ready to turn our surface model into a shell element mesh.

After shell element meshing and applying forces and fixtures to our model, we run the model and find the following results:

Max Stress is calculated at 90.422 MPa
Max Stress is calculated at 90.422 MPa
Max Displacement calculated at 2.112 mm
Max Displacement calculated at 2.112 mm

When examining the results we can see the following comparisons to our solid element study:

MAX STRESS:

Solid Elements – 83.349 MPa

Shell Elements – 90.422 MPa

 

MAX DISPLACEMENT:

Solid Elements – 2.112 mm

Shell Elements – 2.057 mm

 

These results show a variance of less than 10%, which is within our range of tolerance.   However, when we examine the total nodes in the shell element study we see the following:

SHELL BLOG 13

When we created our Solid Element mesh we had a total of 80,052 nodes. We have reduced that number to just 6,352, without sacrificing the quality of the results of our study. This reduction in nodes will result in a significant reduction in the number of calculations, and ultimately a reduction in the amount of time it takes to reach a solution for this study.

 

I hope that you find this summary of why we use shell elements to be a helpful explanation of what nodes truly represent in a SOLIDWORKS Simulation study, and how using a shell element mesh to reduce the total number of nodes can reduce the total amount of time required to solve a study. Remember that for a model to be a good candidate for a shell element mesh, it must have uniform wall thickness.

Mastercam (CNC Software, Inc.) Announces New Leadership

Meghan Summers-West Named President of CNC Software, Inc.

 
Meghan Summers-West has been appointed president of CNC Software, Inc., the developer of Mastercam® CAD/CAM programming software for CNC machine tools. Former president, now chairman, Mark Summers made the announcement to all 139 employees on Thursday, April 2 at the company’s headquarters in Tolland, Connecticut. Its educational division staff located in Gig Harbor, Washington, participated in the celebratory announcement via teleconference.
“As many people close to the Summers family know, this transition has been almost 32 years in the making. My daughter Meghan was born the same year that my brothers and I officially launched Mastercam and established CNC Software, Inc. in 1983,” Mark Summers said. “As a father, I am proud. As a business owner, and to all of you who have contributed so much of yourselves to make this company successful, I am wholly confident in this decision. For the majority of you who have watched Meghan grow up in these offices and have been impressed by her warm and direct leadership style, her curiosity and willingness to learn, her product knowledge, and her overall intelligence, I know that you are certain, too, that the future of our flagship product Mastercam and our organization is in very capable hands.”

Summers also said that with the rapid consolidation of many CAD/CAM companies, this decision represents a continuation of CNC Software’s deep, personal dedication to Mastercam and to Mastercam’s global customer base. He emphasized that appointing Meghan also demonstrates that the company remains a private entity. This is important for both employees and customers as it represents the least amount of potential change for the company.

“We answer to our customers rather than a board of directors, and we intend to stay that way. Today is a very happy day,” he said.

Meghan Summers-West also spoke to the crowd. “Today is two things. It’s an acknowledgment of all I have worked for and desired since I can remember. It’s also, more importantly, the beginning of the next 30-plus years for Mastercam and CNC Software,” she said. “I am honored and excited to take on this role and to continue to work with the sincerest and smartest people in our industry – you and our dedicated and loyal worldwide Reseller network and our bright, innovative customers.

“Mastercam plays a vital role in changing lives for the better. It’s used in all facets of industry, from helping to make life-saving medical devices for the human body to parts for planetary exploration, expanding our knowledge of the universe. Mastercam boosts personal and industrial productivity, supporting our global economy as a whole. Mastercam for educators and students helps train future machinists, engineers, and programmers – people who create, solve problems, and enjoy good incomes and satisfying careers. Mastercam touches almost every person in every place in some way. We are changing the world, one feature at a time. As such, my intention – with your valuable contributions – is to continue to evolve Mastercam by anticipating manufacturers’ and technology teachers’ needs and wants for decades to come.”

Ms. Summers-West has served as Operations Manager at CNC Software since 2009. She earned a Bachelor of Science degree in Business at Bentley College, Massachusetts and an MBA in Management at Hawaii Pacific University. In 2014, the Society of Manufacturing Engineers named her one of the “30 Under 30 Future Leaders of Manufacturing”. She serves on the Young Professionals Group for HVCC, the local food pantry and human services agency. She also participates in the School to Business Partnership as well as interview days and career fairs at several local schools. She resides in Vernon, Connecticut with her husband and their two children.

Current executives at CNC Software, Inc. will continue in their leadership roles. Brian Summers is vice president. Gary Hargreaves is vice president – business development and Rich Norton, corporate controller. Mark Summers will also be involved in the daily operations of the company.

Using the SolidWorks Note Feature to Improve 2D Drawings

Hello Prism Engineering Community,
Toby Schnaars here with another Prism Tech Tip. Today we are going to examine the process of combining dimensions into notes using the SolidWorks Note feature. Combining Dimensions Into Notes Image 1

 

When working in a SolidWorks and using the command INSERT > ANNOTATIONS > NOTE, you have the ability to add 1 or more dimensions to this note text. This dimension text will then appear as part of the note, and any changes you make to the original dimension will automatically update the note, as the 2 will be linked together.

To accomplish this in SolidWorks, simply open a drawing and add some dimensions to your drawing views. These dimensions may either be DRIVING DIMENSIONS (from the model) or DRIVEN DIMENSIONS (newly created in the drawing).

Combining Dimensions Into Notes Image 2

Next create a new note (INSERT > ANNOTATIONS > NOTES) and begin typing some text.

Combining Dimensions Into Notes Image 3

When you are ready to add the DIMENSION info to the NOTE text, move your mouse out onto the screen and single left click the desired dimension. You should see your dimension text added to your note.

Combining Dimensions Into Notes Image 4

This functionality works for both DRIVING and DRIVEN dimensions, and any changes you make to the original dimension (for example, adding a bi-lateral tolerance to the driving dimension) will be automatically propagated to the NOTE, via the linked text.

Combining Dimensions Into Notes Image 5

Once the dimensions are combined into the note with the desired display, you may (optionally) utilize the command VIEW > HIDE/SHOW ANNOTATIONS. This command will allow you to single click on any visible dimension in your drawing, changing it a very light grey. Once you choose the command VIEW > HIDE/SHOW ANNOTATIONS again, you will exit the command, and all the dimensions you selected will be hidden completely.

2015-04-06 Combining Dimensions Into Notes Image 6

To view these hidden dimensions launch VIEW > HIDE/SHOW ANNOTATIONS once again and single click on any hidden dimensions. Upon exiting the command these hidden dimensions will return to their previous state (visible).

I hope you find this trick to be a useful way to combine dimensions into a single note, to get the perfect presentation for your SolidWorks drawings. For more great tips tricks and webinars be sure to visit us at www.Prismeng.com.

Have a great day!

Using SolidWorks EPDM Data Cards to Update Excel Documents

Automate documentation of ECOs in multiple documents using EPDM Variable Fields

We all know that SOLIDWORKS EPDM can store files created by Microsoft Excel, but what if there is information in the Excel file that we want to display in the file’s EPDM data card or vice versa?

SolidWorks EPDM allows the user to create a relationship between Excel, Word, and SolidWorks content and EPDM data cards, enabling the user to update multiple documents by editing just one EPDM data card field.

Is there anything special we need to do with EPDM variables to make this automated update process work? Is there anything special in Excel we need to do? In this article we will find out how to make EPDM data cards communicate with your excel file:

Overview: Entering ECO data in one EPDM data card to update many documents

A good example of why you might want to push data from a data card into an Excel file is if you are using Excel to document an engineering change. In this example, we will do just that.

I have created a template for new ECOs (Engineering Change Orders). This template brings up a data card that prompts the user to enter information about the engineering change:

using epdm data card to update excel

This data should then be used to populate fields in the data card rather than the user re-typing all that information into the Excel file. Our philosophy should always be to create a single point of entry, meaning enter the data once and have EPDM leverage that data elsewhere automatically.

In this example, when I select the “Create File” button, this is what I get for my Excel-based ECO:

using epdm data card to update excel 2

 

 

The text that has been pre-filled into the Excel file came from the data card:

So, how did all this loveliness happen?

Procedure: Link Metadata fields between your EPDM data card & Excel

Excel can store and use metadata just like EPDM and SolidWorks can (This is also true for Word). The metadata for Excel and Word is called custom property, just like in SolidWorks.

We’ll take a look at just one field in the data card: the “Description” field. As we can see, the “Description” field is storing its information in an EPDM variable called “Description.” This Description variable is linked to custom property information called “Description” and it applies to SolidWorks files, .docx, and .xlsx file types. Of course, in our case, we are most interested in the .xlsx file type.

using epdm data card to update excel 3

That’s all that is needed on the EPDM side. Let’s get the Excel file ready to read the information in the EPDM data card:

using epdm data card to update excel 4

In Excel, when you select a cell, the cell’s name is displayed in the top left corner, just below the toolbar. Typically, it’s something like, A11, B12 or G4… Hey, you sunk my battle ship!!

These are the coordinates of the cell you have selected. You can actually rename a cell and that is what we will do to communicate with EPDM data cards. In this case, the field that will contain descriptive information about the ECO has been renamed to “Description.”

To display an Excel file’s custom properties, go to the home button in the top left corner and select “Prepare” and then select “Properties.”

using epdm data card to update excel 5

Select the “Document Properties” pull-down and select “Advanced Properties.”

using epdm data card to update excel 6

In the property dialog, create a new custom property called “Description.” Then select the “Link to content” check box. This will allow you to choose from the list of named fields in the “Source.” In this list of names, you should see the field we named “Description.” Select “Add” and “Ok.”

using epdm data card to update excel 7

Now, that field in our spread sheet is linked to the custom property “Description” which, when added to EPDM, is connected to the data card field “Description.”

And that’s it! Yet another way to automate our processes and make our lives easier through EPDM.
