The automatic mesh generation function automatically creates a mesh based on analysis and mesh generation settings.
Alternatively, a mesh can be created manually by using the JMAG-Designer Geometry Editor with specifying the number of divisions and element sizes.
This script retrieves the number of nodes and elements for a mesh created in a study.
Preconditions
- One or more studies have been created.
This script runs on the active study in the project tree.
Script Function
- If a mesh has not yet been created for the specified study and case, it executes automatic mesh generation.
- Display the number of nodes and elements of the generated mesh.
