Re: Analysis Challenge – 3D Reaction Pattern
I’ve attached a screenshot below to clarify the geometry and points. The rack has four CGs and these are the load application points (a), (b), (c), and (d) in the spreadsheet. Each CG has a load...

Re: Analysis Challenge – 3D Reaction Pattern
This problem was resolved by the Mathcad community, so I gave Fred the credit for solving it. I've posted the Mathcad express file and a pdf solution if anyone wants to examine it. Now, I just have...

Great work Charles!We hope that PTC will fix the situation in a future patch inside creo 3 or, at least, in Creo 4.This is not a "advanced feature" like hyperelastic material; this thing must work.

Hello, after reading the whole thread again, i realized that i was the one bringing up symmetry constraints to begin with :-). This was not brought up by OP, i just assumed this based on the model...

Shell Accuracy, small radii
Following the e-Learning program. First they say that shells are not very accurate at areas of small radii. Then they say that in comparison with shells, solid elements are not accurate at areas of...

Re: Shell Accuracy, small radii
there are several factors you are dealing with that will throw off your numbers. Most importantly is the facet size and distribution. That is what the analysis is done on. Small rounds and fillets...

Re: Shell Accuracy, small radii
I would start with shells (if possible) and even take out the small radii at first. Then see what the stress in your model looks like. These radii probably don't cause any stress concentrations at all,...

Thank you for your reply Christopher. Your answer made me think a bit more about this. Like you, I don't do contact analyses in Creo/Simulate; in that case Abaqus is my tool of choice. Part of the...

Chris, My hat is off to those that understand the theoretical mechanics at a level I struggle to remember and then they code it as well. I can't do that. What frustrated me was the rapidity with which...

Hi Charles & all, unfortunately, like you recognized, there are still many limitations in combining different nonlinear functionality in Simulate. You may find some useful information for your...

Hi Charles, To be honest – I don’t know why this work has been branded as PTC internal only, I even did not recognize this when I worked for PTC, and I do not know who was responsible for this...

Family Table Grays Out after Saving in Simulation?
I was working on a Generic, entered Simulation, created some forces/constraints and ran a simulation. I saved the file. I thought I was out of simulation and found the Family Table grayed out. I...
