Dear stko team, I am currently applying loads via Faceforce and performing analysis. Could you please explain the relationship between the duration of time-series load application and the duration of the computational analysis?

Therefore, I wish to replace it with a constitutive model that better simulates saturated sandy soils at considerable depths. Do you have any constitutive models you would recommend?
You should understand what model you need in OpenSees (it's not about STKO).

Additionally, you mentioned that ...

This one works:
pm4sand.zip

There were 2 issues:

You forgot to put the tag of your PM4Sand material after the FirstCall argument in the setParameter command. The PM4Sand only processes the first argument if the second argument is equal to its tag:

Now you cannot use the ...

Please reply to me here; I look forward to hearing from you.

Can you share your STKO model?


Right, I've just posted a new topic with the following content:Dear stko team, I am simulating a two-dimensional soil mass using PM4sand material and SSPquadUp elements. However, I encounter errors during the elastoplastic calculation. Despite extensive ...

I encountered the same issue. May I ask if it has been resolved?

Hello, I am encountering the following error during calculation after executing `updateMaterialStage -material 2-stage 1` when using PM4sand material and SSPquadUP units. I am unable to resolve it and urgently require your assistance. Many thanks in advance!
