Dear SimScalers,
in this week’s spotlight, we take a look at a finite element simulation of a Roller Bearing by our partner and PowerUser Ben Lewis (@BenLewis ).
Check out our partner: https://www.simscale.com/custommachines/
\underline{\textbf{Introduction & Problem Specification}}
Ben wanted to see how the rollers carry a radial load as they move around the race. To achieve this the rollers don’t actually roll, they are incremented in small steps over time. Another approach will be presented which has been carried out by our Application Engineer @ahmedhussain18 with the same simulation of a Roller Bearing.
This project spotlight is divided into the following parts:

Geometry

Meshing

Simulation

Simulation with SimScale

Results
\underline{\textbf{Geometry}}
Format: STEP
Figure 1: SimScale model
Figure 2: KeyShot rendering
\underline{\textbf{Meshing}}
Type: Tetdominant
The mesh of the model was executed with the TetDominant allround meshing algorithm, mostly dedicated to structural mechanics, which can also be used to generate tetrahedral meshes with boundary layers for fluid flow analyses.
Nodes: 131,086
3D elements: 293,239
Contact slave nodes: 2184
