Problem with CORD4R?

jmborlot

Hi everybody,

I think I have a problem with CORD4R… it seems to be ok on Hypermesh screen, but the results are not..

I have defined a local Csys to apply a local YZ load (small angle of nearly 6.5°) on my model, but when I check the applied loads in optistruct output, I get a global X load. I have a look at the documentation, where CORD4R seems to be a mix of CORD2R and CORD3R considering explanations and figures.

For what I see, CORD4R "C" point seems to define local X axis for Hypermesh, while defining local Y axis in Optistruct…

Any feedback from CORD4R users?

(v2025.1, hypermesh + optistruct on win11 for this job)

Hello,

The CORD4R export functionality in Hypermesh is undergoing improvements and will be updated in the next release.
