Hello, more of a conceptual question I am struggling to figure out: Using MPI, I have computed a scalar solution, u - of which I understand is currently distributed across all processes. Problem is, I need to be able to evaluate this function u on all processes at an arbitrary point P(x,y) (P is d…

Consider something as the following. This code first checks if there is any cell on the process containing the point, then, if the point is found evaluates at this point. If the point is not on the process, it returns -1 import numpy as np from dolfin import * from IPython import embed mesh = Unit…

Hi dokken, Thank you for your reply, Correct me if I am wrong, but does the code in the post you linked not only work if the point P is the same on each process? As in, all procs are concurrently looking for point P across each partitioned mesh, evaluating it if they find that it collides on a cer…

Hi dokken, Thanks for this solution - It doesn’t quite do exactly as I needed but it helped me think of a completely different way to do what I needed to do! Cheers,
