Tip #1: Common meshing issues – sleeves
Having trouble getting your high-pressure die casting simulation to mesh in Altair Inspire Cast? The problem may be in long, thin geometric features. Specifically the sleeve on a hot chamber shown in the example below.
Typically, a die that has a hot chamber sprue will have a sleeve associated with it. In the real world, this sleeve covers the heating elements. In the simulation world, this modeled geometry adds unnecessary complexity by causing sections of the mesh to have zero thickness or force you to use a much denser mesh than necessary for the part. That being said, it has to be removed.
Using the geometry tools in Altair Inspire Cast, we can easily remove this sleeve with a few cuts and modifications.
The resulting part should have no problem meshing and not compromise the integrity of the overall simulation.
That wraps up the first quick tip in this series. Up next, we take a look at another common meshing issues: vents. Check it out here.
