How to extrapolate variables to other points?

How to extrapolate variables to other points?

How to extrapolate variables to other points?

(OP)
Hi,

I'm trying to define a new variable with Abaqus to visualize it : it's the multiplication between a tensor and a vector field but the problem is they're not defined at the same points. The tensor is defined at integration points and the vector is defined at nodes.

I think I should use the user subroutine Ufield or Usdfld but I don't understand how to it.

I welcome any ideas.
Best regards

M.

RE: How to extrapolate variables to other points?

Hi M,

I already had that kind of problem (multiplying tensors calculated at different points) but I didn't succeed with Abaqus (time lacking) so I did it with Comsol Multiphysics. It was a lot easier so you'd better try this way provided that you have it.

Anyway, i'd be curious to find out how to do it with Abaqus.
