Hello Christopher,

thank you! Now the weighting CoefficientFunction works.

For linear problems the everything works as expected but I want to apply the element weights to nonlinear problems as well.
When calling AssembleLinearization of the BilinearForm I get the following error:

Code:

    K_weighted.AssembleLinearization(u_full.vec)

Evaluate AutoDiff<double> not overloaded, type = class ngfem::MyElementWeightCFin Assemble Element Mat, bfi = Symbolic BFI in AssembleLinearization

Is there a way to make AssembleLinearization work with the custom CoefficientFunction?

Best regards
Nils

Hi
for this derive your function from CoefficientFunctionNoDerivative instead of CoefficientFunction
