3D Baroclinic Solver

3D Baroclinic spectral solver

The 3D baroclinic spectral solver is now operational! It is based on a fully implicit 3D semi-linearized wave equation, and thanks to the now-a-day available optimized linear system solvers, it is an extremely cost-efficient way to model internal waves.
