A Meshfree Method for Simulating Myocardial Electrical Activity

Figure 5

Convergence behaviours of EFGM using different background mesh. ℎ is the spacing between nodes. RMS is the error measure. It shows that 2×2 Gaussian quadrature scheme in each cell of fine background mesh works a little better than 4×4 Gaussian quadrature scheme in each cell of coarse background mesh.
