He fed Flow 3D Cast Advanced the CAD geometry, the gating system, and a recipe of alloy thermophysical properties. He chose a fine mesh around the channels, switching to a coarser grid elsewhere to save time. Boundary conditions mimicked the sand mold’s permeability and the inert atmosphere in the pouring chamber. He enabled the software’s shrinkage and porosity modules, activated the solidification model, and let the job spin.
