Surface Mesh Face Rotation Angle Limit
Surface mesh face rotation angle limit sets the face rotation limit angle for meshing discrete models.
In order to mesh discrete models, mesh modifications on the initial discrete surface mesh definition are carried out. A modification is not allowed if it rotates an existing mesh face by the face rotation limit. By default this limit is set to 15 degrees and you can modify this as needed. A smaller limit implies that the initial surface definition will be adhered to more closely, at the possible expense of other mesh attributes such as mesh size. Remember this setting is only applicable for meshing discrete models.
