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.
