As a first step we need to create a new simulation. To create a simulation left click on the bearing block and then on Create Simulation.
Bearing block geometry and geometry log
This dialog box allows the user to select the simulation model. Click on Static.
The default settings for the simulation are kept the same. Save the simulation model by clicking on the tick mark.
Left click on the mesh icon to create a new mesh.
Choose the Tet-Dominant Algorithm and the desired mesh order (First order).
Select the overall automatic sizing and the desired mesh fineness ( 2-Coarse in this tutorial)
Specify the Number of computing cores for the meshing operation (16 in this tutorial)
Click on Generate to start meshing. The progress of the meshing is shown in the bar.
Once the mesh is generated, we can check the event log for further information on our mesh.
The generated mesh is presented below. The mesh has 139.9k cells and 27.7k nodes.
The resulting mesh for the bearing block shows a reasonable discretization of the geometry and may now serve for a first simulation setup.
However, as we can see, some parts such as the small radii are not represented accurately in every detail. The number of layers in the radii is only 2.
Although increasing the mesh sizing from coarse to moderate and further might help it would result in higher computation time.
One way to get through this is through Manual Sizing Option which is explained in the advanced tutorial.
The Sizing defines how coarse or fine the discretization of the input geometry will be. For the automatic sizing the mesh size varies from very coarse to very fine. Go through the meshing page for Tet-Dominant meshing for more information on sizing.
