Summary
This PR fixes an issue in the IGA–FEM Nearest Element Mapper related to the evaluation of shape functions and the corresponding equation IDs when using NURBS surfaces with polynomial degree p > 2, inside
projection_utilities.cpp.The bug led to incorrect local support handling in the projection utilities, which resulted in:
