What will GETVRM return for an element with multiple integration points?

[theoouyang]

Hi,

I am trying to write a user subroutine in Abaqus, but I got confused with some of the definitions in the Documentation.

GETVRM('S'.........) will return the stress components at the material point of the element, and many Abaqus users say that the material points are actually the integration points. So what will GETVRM('S'.........) return for an element with multiple integration points?

Thanks.

The main subroutines (like USDFLD) that can call GETVRM, runs for each integration point separately. That means in each run GETVRM will report the values of that integration point only.

To Mustaine3,

I seem to understand what you mean now, and correct me if I am mistaken: it means if within one element there are n integration/material points, USDFLD will run n times for that element, once for each integration/material point.

Cheers.

That's correct.

You can output the element and integration point number that is processed in each run.
