 Enable refinement of polylines to create a better representation of curvilinear boundaries (e.g. in free-surface problems).

 Set tolerance for refinement of polylines to create a better representation of curvilinear boundaries (e.g. in free-surface problems). See tutorial for interpretation of the refinement tolerance.
