The pressure distributions of the compressed block benchmark (Section 4.1) for the FE (P1/P1) solution (left) and for IBFE solutions corresponding to the modified case with stabilization (middle) and the unmodified case without stabilization (right). We show a coarse and fine discretization and use P1 elements for each method. Results from all formulations appear to be converging to the same solution. The IBFE method uses m = 1089 DOF and m = 9409 DOF for the coarse and fine cases, respectively. The FE method uses m = 1089 DOF and m = 16,641 DOF for the coarse and fine cases, respectively.
