Re: Nonlinear Contact Analysis
Thanks for the input, Charles. I have the components of the assembly mated (edge to surface) so there are no gaps initially. I guess I assumed that when the program uses one of it's material laws,...

Ive been able to make some progress I think. Ive got an mechanism analysis made with a playback where I drop my hammerhead onto my fixture plate using gravity, and 3D contact surfaces on the...

Whether you can do this in Simulate depends on several factors: Physics associated with the system.How the system is designed (assembly methods, materials, etc.)Type of results you're after.Accuracy of...

Thank you, this is really helpful. We have the resources but its hard to get the professors time to learn to use them. We use creo at school exclusively but we were only taught in making models and...

Hi all, I need some help. I am using Creo/Elements Pro5.0 ( I do have creo 3.0 but it is on a machine she currently does not have access too). I am teaching my daugther Creo Simulate and she...

Go to File>Properties>Units and select Info, as shown in the below example. This will give you all the units of measure (click to enlarge).

Chris, I think Creo will interpolate within but not extrapolate beyond UTS. Raising the UTS may get it to continue. The large resulting strains will require finer mesh and longer run times. Can anyone...

Hi, It does not seem possible to have both a radiation and a convection condition on the same surface? It is physically meaningful. Is this right? Thanks Charles

Charles, Have you looked at the Mentor Graphics Flo/EFD add-on for Creo?It's limited, but does expand Creo's ability in this area, though I wish it would do some non fully filled media solutions (like...

Yup, Newton's 2nd law must be obeyed F=ma 1N=1kg x 1m/s^2 if you use mm then to still get 1N of force you must have 1000kg (1mm is 1/1000m and therefore the acceleration is 1mm/s^2 which is 1/1000th...
