Dear Joachim,
Thank you for the response. This works. I do have an additional question.
Now that I’ve used IntegrationRuleSpace the data in gfuir.vec.data is equal to the actual u,p values as opposed to polynomial coefficients in the original gfu.vec.data.
However, I am not sure where the spatial data corresponding to these values is stored.
Normally with the original gfu I’d evaluate it like:
gfu(mesh(p1,p2)) or gfu.components[0](mesh(p1,p2))
For gfuir this won’t work.
Is there another way to obtain the corresponding spatial locations of the values?
