A Meshfree Method for Simulating Myocardial Electrical Activity

Figure 6

Results of conduction velocity using FDM, FEM, and EFGM. h is the spacing between nodes and RMS is the error measure. It shows that EFGM still has better convergence rate after the reaction term is included than FEM and FDM. 2×2 Gaussian quadrature scheme in each cell of one finer background mesh is applied.
