I want to use it to simulation irregular surface

[ALY-127]

Dear Author
Hello, prafessor, I want to use DG to simulation seismic wave for irregulare surface, and product shot record. I do not know it can be or not. Because I do not good at Fortran, I perfer to C++ or python. I find it is simular to SPECFEM2d

Dear ALY-127,
the advantage of the DG method over the spectral element method that SPECFEM is using, is that it is very easy to create suitable meshes for complex geometries including rough surfaces. So it should not be a problem to create an appropriate mesh with your favorite mesher (e.g., Gmsh).
You can place sensors anywhere in the model or at the surfaces. So it should not be a problem to get the shot record for your desired survey layout.
Please read the manual and run the examples to see what NEXD 2D can do.
Best
Marc
