CATIA V5-6 FEA Tutorial Bearing Load with Adaptive Mesh

Dassault Systèmes CATIA V5-6 FEA Tutorial

Applying a Bearing Load to Part as well as adding an Adaptive Mesh

1. In this tutorial we will be making a simple part and applying a bearing load to the hole in the front of the part and clamping the back. 
2. First make the part, the dimensions are shown in the beginning of the video or feel free to make up your own. When switching from the part design workbench to the generative structural analysis toolbar and select the static analysis. An OCTREE Tetrahedron Mesh is added to this part as well as a 3D property. When choosing a mesh size select it to be parabolic because parabolic meshes have more nodes and work better for circular and curved surfaces. Parabolic meshes also have 3 points on each edge of the tetrahedron. 
3. To view the mesh size you have selected simply right click on Nodes and Elements and choose mesh visualization. Make sure to deactivate the mesh.1 in the tree by right clicking on it before continuing the tutorial. 
4. A bearing load is then selected as the load being applied to the part. For this case select 100N and apply the bearing load to the inside face of the hole. The angle setting allows you to decide which way the force will be applied. Simply adding a negative sigh to your force will flip the force in the direction in which the sign is added. 
5. Add a clamp restraint to the rear face of the part. 
6. Check mesh size to ensure it the proper size you desire then compute. After the part has computed click the static case solutions. Select Deformation, Von Mises Stress, and Translational Displacement. Notice when selecting the Translational Displacement that it comes in as vectors, simply click a vector and change the selection to average ISO. 
7. Use the Images Layout tool to move apart the static case solutions so they can all be viewed together. 
8. Then we are going to compute with an adaptive mesh. Note that you have to compute normally before you can compute with adaptivity. 
9. Select the Adaptively Tool and select mesh you want to use. Add desired % error goal. Compute normally first then compute with additivity. Give the number of iterations and minimum mesh size. 
10. To view the static case solutions as an animation use the Animation Tool located by the Images Layout Tool. I prefer to slow down the animation by increasing the number of steps to the max of 50 and then selecting my own duration which 1s works well.
