Summary: Enable Volume-based Autosizing, which allows greater control for external flow simulations.
Flag:
mesh_volume_autosize A
A = 0: Default. Volume-based Autosizing is disabled.
A = 1: Enable Volume-based Autosizing
Description
To force a finer mesh in regions that are not closely bounded by geometry, such as in many external-flow simulations, enable Volume-Based Autosizing. This additional refinement better controls how elements grow from the walls into large, open regions. While the resultant mesh count may be higher, the solution accuracy is generally improved.
