Solution space is determined by the refinement. If a NURBS patch is the underlying geometry of the respective Design / Design BRep element, the polynomial degree (p,q,r) and the knot vector can be manipulated for every direction in the parameter space (u,v,w).

Parameter Description

Parameters
Parameter Values, Default(*) Description
dp, dq, dr int
auto
degree elevation by int
automatic degree elevation accordingly to underlying NURBS patch (only for DE-BREP-EL)
ep, eq, er int final polynomial degree
ru, rv, rw


gu,gv,gw
int
<float, float, ... >
auto
float
number of knots to be inserted per element
knots to be inserted
automatic knot insertion accordingly to underlying NURBS patch (only for DE-BREP-EL)
approximated element size in geometry space
