How to improve analysis time.

Post by jpereirasan » Fri Mar 28, 2025 12:35 am

Hi Stko Team.
I'm running a Slope Model with SSPQuadUP elementes and a Lysmer Kuhlemayer dashpot. (Following the OpenSees wiki example)

The model is taking a lot of time to run even in powerfull computers. ( 1 hour to calculate just 1%)

Can you please check the Analysis command or can you give me suggestions to improve the run time?

Unfortunately is due to the huge amount of internal iterations the PDMY02 material is doing for the plasticity return mapping. You can verify this by doing a test without updating the stage to plastic.
Double check your material parameters to understand why this is happening
