RBsolve is a CFD code for Rayleigh-Benard (natural convection) problem simulation with Boussinesq approximation. The code is written in Fortran and solves a system of coupled equations for momentum and temperature in the incompressibility hypothesis. Introduction of a second active scalar (for solving a double diffusive problem) or of a constant lapse rate or radiative cooling are additional available options.
This release includes non-homogeneous vertical boundaries and infinite Prandtl options.
