Global Mesh Settings

Mesh settings is the section that allows the user modify the resolution and tessellation of the mesh engine. This section discusses setting the properties for the Global Mesh settings, which is applied to the model in its entirety. It is not until a Local Mesh group is created that these will override the Global Mesh settings.

The main 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.
