Displacements and von-Mises stresses from numerical solutions with and without basis removal in the Neumann problem using \(C^1 Q^2\)-splines and mesh size \(h=0.1\). In the detailed view we note poor quality of the stresses on the boundary in the standard solution which is remedied when removing the problematic basis function. a Standard solution. b Detail in standard solution. c Basis removal solution. d Detail in basis removal solution
