Boussinesq fluid primitive equation model

This is a simple model of Boussinesq fluid primitive equations with Newtonian cooling and heating for radiative process. This program is written in Fortran90. Spectral method is used for horizontal direction and central difference method for vertical, the 4th order Runge-Kutta method for time-integration.

For details of equations and numerical methods, read the appendices of my master thesis here (in Japanese).

Usage

1. Install the dependent libraries shown above.
2. Copy source codes in a directory
   • for axisymmetric 2D version, BPM2D.f90, module_BPM2D.f90, and wrap_lj.f90 are needed.
   • for axisymmetric 2D stiff equation version, BPM2D-stiff.f90, module_BPM2D.f90, and wrap_lj.f90 are needed.
   • for 3D version, BPM3D_omp.f90, module_BPM3D_omp.f90, and wrap_sj.f90 are needed.
3. Modify module*.f90 if needed.
4. Compile BPM2D*.f90 or BPM3D_omp.f90 with linking the dependent libraries.
5. Run a.out
