Dear All

I have some questions about the numerical method in WRF or WRF-Chem models.
If there are any answers or related references please let me know.

1) In which module the discretized equations are solved? Or in which code the equations are discretized?
2) Which method is used to solve the linear equations systems? For example Gaussian elimination, Gauss-Jordan, Gauss-Seidel, Jacobi, TDMA or ....?
3) Are the pressure-velocity coupling algorithms used in these numerical models? For example the SIMPLE, SIMPLEC, SIMPLER, SIMPLEX, COUPLED or ...?

Best Regards
