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.
