Any part or small assembly(keyword small and not very complicated) takes way too long to get some stress results.

But when i use simulation express it finishes in less than 5 seconds, where as the normal simulation can take 5 or 10 minutes.

Ohh but when i do use simulation express i lose the model sometimes aswell, it brings up all the results but the model is hidden somehow???

Has anyone else had this behaviour, any help would be much appreciated

Thanks
