A Meshfree Method for Simulating Myocardial Electrical Activity

Figure 4

All the experiments, including FEM, use linear polynomial basis, and their convergence rates are indicated by slope. All the nodes are regularly placed and so h is the spacing between nodes. 4 × 4 Gaussian quadrature scheme in each cell of background mesh is used for numerical integration.
