Stress gradient in Hyperlife 2025

Robert_Szlosarek

Dear Hyperlife users,

I want to try out the stress gradient feature in an EN-analyses.

The issue is that my cumputers runs for hours without any results. Are the any limitations for the size of the model or the number of analyzed elements?
How is your experience with the stress gradient approach?

Best regards,
Robert

Hello Robert,

This is expected for models with many elements. The computation time will be improved in a future release.

To reduce computation time, run the fatigue analysis with the stress gradient option enabled on a small subset of elements. Delete all other elements from the model file.
