ADVANCED CFD SOLVER

Cast-Designer's powerful Computational Fluid Dynamics (CFD) which is FVM based solver, incorporates many advanced features in the flow the calculation like surface tension effects, viscous shear stress combined with gravity leads to buoyant flow, turbulent phenomena greatly enhance the diffusion of momentum and enthalpy also modelled. For fluid dynamics simulation, the algorithm solves equations of conservation of mass and momentum for any number of immiscible, incompressible fluids, and tracks the interfaces between them, two fluid model (liquid metal + air) effective in bubble formation.
