Hi Austin, No we haven’t done that. I have implemented DPG but only in the mixed formulation with the residual as an additional variable, which avoids the need to compute optimal test functions explicitly.

Has anyone in the community done this without solving for the optimal test functions over the global problem? i.e. they have been able to use Slate to perform the element-wise computations to compute the optimal test functions that will be used in the global solution as DPG FEM would require. If anyone has ideas how this could be implemented let me know.
