Figure 3:

The three components of the deviatoric part of σe for the compressed block benchmark (Section 4.1). The IBFE method uses modified invariants and volumetric stabilization (νstab = 0.4). Each row is labeled with the solid degrees of freedom (DOF), and the bottom row depicts the FE (P1/P1) solution with m = 8385 solid DOF (higher than that of the highest resolution IBFE results presented in this figure). We use P1 elements for each method. The results from the IBFE formulation are clearly converging to the higher-resolution FE solution.
