TCFD solver for steady state, incompressible fluid flow is called blueSolver. It was gradually developed during the time from the simpleFoam solver. In any matters the blueSolver behaves the same way as any standard OpenFOAM solver. It is compatible with all OpenFOAM applications and libraries. Solver is modified to be more robust, it can use MRF method, limits for variables can be specified and many other changes have been done.
