Dear Christopher,
I'm working on the C++ side, and I was wondering is there a way to get the coordinates of the vertex of the element inside the function CalcShape and CalcDShape.
Kind regards,
Umberto

Hi Umberto,

if you have a MappedIntegrationPoint, you can get the ElementTransformation from it, and from the ElementTransformation you can get the Mesh and the ElementId.

A short example is attached.

It uses the brand-new feature of including C++ code in Python scripts.

Hi Umberto,

we can now do it by refining the mesh, and keeping the pressure in the range of the prolongation operator.

I added the method to the Stokes-tutorial, available in the latest nightly docu:

Dear Joachim,
is there a way to implement the prolongation operator also for the custom elements that I've implemented using mylittlengsolve ?
Kind regards,
Umberto
