1. The problem statement, all variables and given/known data I have to simulate an isothermal filling of a cavity using Autodesk Mouldflow Insight. 2. Relevant equations 3. The attempt at a solution I tried setting the mould temperature to the melt temperature but I do not seem to get a reasonable answer as the cavity will fill regardless of the packing pressure. I do not seem to get a reasonable answer either when I set the flow rate and allow AMI to calculate the injection pressure.
