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 and the knot vector can be manipulated.

Parameter Description

Parameters
Parameter Values, Default(*) Description
dp int
auto 		degree elevation by int
automatic degree elevation accordingly to underlying NURBS patch (only for DE-BREP-EL)
ep int final polynomial degree
ru int
<float, float, ... >
auto 		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)

Example of a Complete Input Block 

!===================================================================
!      DE-EL-ID   dp=     dq=    ru=<>     rv=<>
DE-REFINEMENT
 DE-EL    1       ep=1                     ru=1 
 DE-EL    2       dp=1    dq=1             ru=3      rv=3
 DE-EL    3       dp=3    dq=3   dr=3      ru=2     rv=<0.5, 0.9>   rw=1  
 DE-BREP-EL   1	  dp=auto                  ru=auto
 DE-BREP-EL   1	  dp=2                     ru=10
