Contour plot of strains
I feel very embarrassed to ask since this must be an incredibly basic thing, but how do I get a contour plot of strain from HyperMesh (using results of an Optistruct model)? I can get contour plots of stress easily enough, but strain just seems to not be an option. I have tried activating the Strain Global_output_request…

Can I assign different contact models to different particle–particle pairs in a single simulation?
In the EDEM GUI I only seem able to select one particle–particle model and one particle–geometry model for the whole simulation. I have two particle types (A and B) and I’d like A–A to use one contact model and A–B / B–B to use another. Is this possible without coding a custom model? If not, what’s the recommended…

Hypermesh heat transfer contact conductance issue
Hi, I’m performing a steady-state heat transfer analysis in HyperMesh 2024.1. Currently, I observe a very small temperature gradient in my results, and I suspect it might be a visualization artifact from the software. My assumption is that even if shell structures are perfectly joined, a contact definition is still…
