I think most of us use the default 80% of injection pressure for packing pressure in the first simulations of a product.   Sometimes the injection pressure is not too high and thus the packing pressure would not be enough to compensate shrinkage properly. (Below 30-40 MPa).   I would like to suggest adding a "Minimum packing pressure" option to avoid unnecessary reruns of simulations because of improper packing pressure.   So if 80% of injection pressure is below the specified "Minimum packing pressure" value, then the minimum packing pressure value would be used instead.   I know with experience you can estimate pressure, but with more injection locations and on a big and complex part, it is not easy, but the computation time is high.   Thank you!       Show More
