A Meshfree Method for Simulating Myocardial Electrical Activity

Figure 10

Propagation wave at 47 ms, 95 ms, 176 ms, and 236 ms with irregular sample nodes (1106 nodes). Fiber orientation from column 1 to column 5: (0.57735, 0.57735, −0.57735); (0.57735, −0.57735, 0.57735); half is (0.57735, 0.57735, −0.57735) and half is (0.57735, 0.57735, −0.57735); isotropic; isotropic. Except 3³ quadrature points in each background cell are applied in column 5, 2³ quadrature points in each background cell are applied in other columns. In each column total 10³ background cells are used for integration of Galerkin weak form. Diffuse parameter: column 1, 2 and 3: 𝑑_𝑓 = 4, 𝑑_cf =1,   column 4 and 5: 𝑑_𝑓 = 𝑑_cf = 1. Red color represents active state and blue color represents quiescent state.
