We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi,

The default 0 in the mesh details window is to indicate that the software will automatically determine the appropriate element size based on the geometry and meshing controls set by the user. This depends on the default sizing options such as the Bounding Box Factor and Surface Area Factor and minimum edge length in the dialog box. You can modify the default mesh size by modifying these details under sizing option. The default mesh is not uniform. So it is not feasible to know the exact mesh size.

Thanks
