so far i have developed a more or less complex fortran code to simulate the wave propagation. But now, there arose problems , regarding to the grid resolution. I need a very high resolution. All matrices, used in the model, are actually sparse matrices. And so does anybody know, where i can get (for free) libraries for handling sparse matrices or which is capable and which is not capable?
Please, help me. Otherwise, i have to rewrite my model in C++.
