Running MoldFlow Express on a single plastic part in SWks 2006 can result in an analysis that takes me from 5-25 minutes on an old Dell M60 @ 1.7 GHz (if I remember it right). That's not bad, as MFExpress is free, and I don't run a lot of analyses everyday. My Questions: 1. On new Dell Laptops (M6300) and XP or Vista, has anyone run the full Mold Flow package for filling analysis? 2. Is it running faster on XP/SP64 or Vista? 3. Does it meet your expectations for speed & performance? I am finally thinking I need the full package so I don't have to make as many compromises in part designs to leave room for "corrections". Thanks - Bo
