[en] The need to calculate turbulent recirculating flow fields in two or three dimensions arises frequently at General Atomic Company (GA). The MINT finite difference code, recently purchased from Scientific Research Associates (Glastonbury, Connecticut), can often meet this need. In its present form the code solves the full Navier--Stokes momentum transport equations, the mass and energy transport equations, and two additional transport equations which model turbulence. MINT efficiently handles turbulent wall layers and implements most standard boundary conditions with a minimum of user effort. Flow geometries must be simple. Each boundary surface must coincide with a grid point surface, and no reentrant corners are permitted. A program to overcome this latter deficiency is underway
