Hi Uri,

Can you please check the case definition. The riser cannot be outside the mold, how can you hold the melt ? It has to be either a sleeve or mold for the melt to hold

1. When I make the Mold top height the same as the risers, (As in reality) the mesh fails.

If I make the mold higher than the risers I miss the air cooling effect because of mold isolation.

Please check and advise.

2. What about an answer regarding the Niyama problem?
