Usage

Each program has complementary parameter file (.par) and should be at the same directory with programs file. In general the steps to conduct the simulation

Step 1: Define parameter
Step 2: Run programs
Step 3: Visualization
Detail usage could seen in example script for simulation.

Version History

1.0.0 (27 Jan 2021): contains programs for wavefield and shot modeling using Finite Difference Method (FDM) and Spectral Element Method (SEM) both 2D and 3D Acoustic case. Numerical dispersion is tackled very well by SEM, eventhough the computation is little expensive. In this version, with and without surface related multiple option is available. Spectral Element Method for P-wave 2D Marmousi model using single and multiprocesors examples are provided, as well as geometry assigment and SEGY export.
