In this lesson, learn the proper workflow to upload a SOLIDWORKS assembly to the 3DEXPERIENCE platform and perform a Mechanical Scenario Creation study using the Abaqus solver.

Open a SOLIDWORKS assembly that has not been saved to the 3DEXPERIENCE platform.

Upload the SOLIDWORKS assembly to the 3DEXPERIENCE platform. Save the assembly in your Collaborative space. Use an existing Bookmark. Return to your SOLIDWORKS desktop. Lock the assembly and all reference components.

Launch the Mechanical Scenario Creation App for the SOLIDWORKS task pane.

View and set Simulation study preferences and solver units. Define the Finite Element Model or FEM Rep. The FEM Rep consists of the Mesh, Material Definition and references the CAD geometry of the model. Create a Global mesh (Tetrahedron second-order elements). Create a Static Step. Apply AISI 1020 material to the bar and base plate of the assembly.

Create two virtual bolt connectors with nuts. A bolt connector joins multiple bodies together or to the ground. The bolts and nuts are not modelled. Bodies joined by the bolts and nuts should have contact interaction defined between them to prevent interference and bonding.

Create a Surface-Based contact. Surface-Based contact defines the interaction behavior between two discrete surface regions in the model.

Apply a Fixed Displacement Boundary Condition. Apply a Remote Force (1000N) to a Split Line feature.

Run the Simulation study. .Use the Physics Results Explorer App to manage results data from Simulations performed within the 3DEXPERIENCE platform. Create three Simulation plots: Von Mises Stress, Factor of Safety (FOS) and Displacement.

Analyze the Simulation plots. Save the Simulation study to your Collaborative space. View the items of the Simulation study saved to your Collaborative space.

Launch 3DEXPERIENCE platform and SOLIDWORKS

The 3DEXPERIENCE platform is browser driven. Your existing cookies and cache determine what you will see on your computer desktop or during a SOLIDWORKS login. A full installation of SOLIDWORKS 2019 SP0 or later is required
.

Start a SOLIDWORKS session from your desktop.

Double-click the SOLIDWORKS icon.

View the illustration below. Depending on your system setup, cookies, and cache, it will be different. Read the provided information.

Input the requested data. Click Accept All.

The Welcome – SOLIDWORKS dialog box is displayed.

You are logged into the 3DEXPERIENCE platform.

Close the Welcome dialog box.

Click the center of the Compass. Launch the Mechanical Scenario Creation App. Think of this App as the SOLIDWORKS Simulation Add-in inside of SOLIDWORKS. Most of the 3DEXPERIENCE Apps run in your web browser. 3DEXPERIENCE Simulation Apps perform a small installation on your windows machine. Both types of Apps are linked to your PLM data on the platform.

Drag the slider downward to view the Mechanical Scenario Creation App.

Launch the Mechanical Scenario Creation App. Note: If this is your first time using a 3DEXPERIENCE Simulation App or an update is available, download the needed App information on your computer. It is recommended to restart your SOLIDWORKS session.

Double-click Tetrahedron Mesh.1 from the Simulation study tree.

View the default settings in the Tetrahedron Mesh dialog box. Mesh refinement is very important in regions of high stress concentrations such as regions of contact or sharp corners. Typically a smaller element size yields more accurate results, but increases the run time. View the default Mesh size (length of one side of a tetrahedron in a mesh). View the default Absolute sag size.

Absolute sag is the difference between the face of your geometry and the highest point of your mesh element. By reducing the value, you are allowing the elements to conform to the organic shape of the geometry.

Quadratic Tetrahedron element order is selected by default.

Click OK from the Tetrahedron Mesh dialog box.

Static Step.1

Create a Static Step.

Click Static Step from the Command box.

The Static Step dialog box is displayed. Accept the defaults. Note: A Static step performs a stress analysis of a stable problem in which inertia effects are neglected. During a Static step, a time period is assigned to the analysis. This is required for cross-references to the amplitude options, which can be used to determine the variation of loads and other externally prescribed parameters during a step.

Click OK from the Static Step dialog box.

Results

View the results. The Von Mises Stress contour plot is displayed by default.

In this example, use the results plots for the Von Mises stress, Displacement and Factor of Safety (FOS). Verify that the Von Mises stresses do not exceed the material’s yield strength. For most metals, the yield strength is defined as the stress point at 0.2% strain offset. For AISI 1020 steel this is (3.516 × 108N/m2).The maximum Von Mises stress (3.29 × 108N/m2) is below the material yield strength of (3.516 × 108N/m2 ).Basics of Stress Limits for 3DEXPERIENCE – YouTube

Click a point on the model as illustrated. The mouse cursor automatically acts as a probe.

View the Von Mises Stress at that point. A Pop-up menu is displayed.

Click the Show Min/Max Values icon.

Click the Hide Max or Min values and close icon.

Display the Factor of Safety (FOS) contour plot next to the Von Mises Stress contour plot.

Click the Changing Plot combo icon to display multiple plots.

Create the Factor of Safety (FOS) contour plot.

View the results.

The FOS plot displays how close a material is to yielding. The factor of safety is calculated by dividing the material’s Proof (Yield) Strength by the Allowable stress.

The FOS plot has a maximum limit of 2 by default. Regions of the model with a FOS larger   than 2 are displayed in gray. Regions of the model with a FOS less than 1, develop stresses above the material’s yield strength under the current loading conditions.

The smallest factors of safety occur in the localized regions where the highest Von Mises stresses occur.

Create a Displacement contour plot. Note: In SOLIDWORKS Simulation the URES Resultant Displacment and the Displacement in 3DEXPERIENCE Simulation represent the same displacement components. Displacement Component 1, 2 and 3 in 3DEXPERIENCE Simulation represent the same displacement components as UX, UY and UZ in SOLIDWORKS Simulation.

Save and Close

Save the Simulation study.

Click the Share icon as illustrated.
