Language and environment: Fortran 90

This is a sample program of The Decomposed element free Galerkin method compared with the finite difference method for elastic wave propagation, by Katou, M., Matsuoka, T., Mikada, H., Sanada, Y. and Ashida, Y.



Here, we provide a sample code of the DEFGM (Decomposed Element Free Galerkin Method). The flow chart of the sample program defgm.f90 is described in Figure 4. It computes Rayleigh wave in section 7. The four side of calculation space is the free surface and there is no absorbing boundary.



This document shows how to use our sample program and change variables. -The decomposed element-free Galerkin (DEFG) method is a highly accurate method for solving elastic wave-equation problems.
