Add Direct Mesh Group

Mesh settings is the section that allows the user modify the resolution and tessellation of the mesh engine. This section discusses creating and setting the properties for Local Mesh Group, which can be applied to specific surfaces or bodies of the model, allowing variable meshing of the geometry. When a Local Mesh Group is created, its settings will override those of the Global settings. Multiple mesh groups can be used if needed.

The parameter concerned by the user is Mesh Resolution (m), which generally sets a cell length constraint by this value and has the greatest influence on the sizing of the mesh cells. Choosing a low value for resolution will generate many cells within your model, producing more physically accurate results but at the cost of solving time and computational resources. You will want to gauge the size of your overall model and pick a resolution size that will generate a decent number of cells per surface or volume, but not an enormous amount so that your computer will struggle with the meshing operation. It is best to start with a larger value and see how well the computer handles the meshing and then work your way down to a realistic number that gives good results within a decent computation time.
