The automatic mesh generation function provides some types of mesh generation method, specifying element size, and element size gradient to generate desired mesh depending on the analysis objective. Additionally, depending on the objective of magnetic field analysis, it’s necessary to consider the mesh modeling of the air region. This script sets up the automatic mesh generation properties for 2D magnetic field analysis using the newest method, Method 3, for automatic element size determination. Method 3 is based on the latest verification and considers both analysis accuracy and reduced number of elements.
Preconditions
- One or more 2D magnetic field analysis studies with motion have been created.
This script runs for the active study in the project tree.
Script Function
- Set the mesh type in the mesh properties to slide mesh and the mesh generation method to Method 3.
- Turn on automatic element size and automatic density gradient.
- Turn on automatic slide division.
