Autodesk does not have a specialized software for die casting.
I have heard the people achieved good results by applying Autodesk Moldflow analysis to die casting. I never tried it myself but from the general principles I would advise:
- Prandtl numbers for metal melts are way smaller than polymer melts. So the inertia is way more important for metals than for plastics. Thus, for die casting only use 3D analysis with inertia terms swiched ON
- Use finer meshes and bias the mesher to get finer mesh on the surface. This is to better catch to boundary layer effect.
- While HTC for polymers molding affect flow only marginally, for the metal die casting it is much more important. Thus, select correct HTC in the Part(3D) properties. HTC for metal casting even dependent upon such things as the thickness of lubricant applied to the mold.
