Figures & data
Figure 1. The exact coefficients μ and the estimated μ on a mesh with 2500 elements. The plots also show the element-wise error and the nodal error.
Figure 2. The exact coefficients μ and the estimated μ on a mesh with 545 elements. The plots also show the element-wise error and the nodal error.
