Oh ok. So the main point is that with default settings you may get better results with Creo 3. This is very good to know.
I haven't done any simulations with Creo 3... yet, but I have worked with Ansys for a couple of years and I agree that it tends to require a bit of experimenting with solver settings from time to time. We are only starting to introduce Creo simulations in our R&D and the aim is to get more and more engineers to do some simple simulations and maybe even more complex ones when they get to know the software. Your comparison shows that there are some good and easy capabilities in Creo Simulate, which may prove to be very useful for us.
Thanks again.
