well from what I have seen, the results for fill (filling pattern, peak pressure, clamp force, air trap and weld line locations, are accurate and fairly similar to MoldFlow’s.
But when you go to Cooling and Warpage predictions most of the times it is significant different, which means in temperature variations of more than 30-40F on the mold hot spots…and ~3-5mm variations on the most warped zones.
Of course you would have to consider the type of mesh you are dealing with, which in my case has to be level 2, for computer capability reasons. In order to have a LEVEL 5, which is the most recommended one for automotive parts, then I will have to have a signficant more expensive computer. However, with a level 5 mesh, I still saw a similar warpage variation between the two softwares.
hope it helps a bit...
