the units are definitley not in mm/g/s. In the results i can see that the mold is moving too fast in the wrong direction and all the dimensions are passed along to the post processor by a factor of 1e-3. By now i can play around to find out what dimensions are used in Polydata (m/?/?) but it would still be nice if someone can describe it to me how to make polydata to use mm/g/s.
