In the past I made several simulations of parts with expected short shots in some very thin areas. Moldflow gives a result of unfilled cavity which slightly differs from the fill time results, concerning the unfilled elements.
The unfilled elements lead to several problems, especially in warpage calculation. The warpage results showed a tremendous amount of deflection in this zone, though it does not contain any melt.
As a workaround I selected the unfilled elements in a tedious process and collected them in an additional layer, that could easily be hidden. Then I displayed the results scaled by frame. Somehow I was able to show reasonable results for the rest of the part, but to reach an acceptable accuracy of this process I needed a lot of work, because of the many steps of switching around between the results and the mesh to select.
Did anyone experience something similar? Or do you have a better idea for solving this?
The short shot areas should be excluded from warpage calculations automatically, at least in the modern versions of Moldflow solvers. Something is not right. Can you check that warpage produces results in the short shot area and if it is true post the model. Just remember that some area can fill during packing stage, etc.
