Detailed Description

template<int sizeres = 10>
class mfem::pLaplaceSL< sizeres >

Implements AD enabled integrator for a p-Laplacian problem. The tangent matrix is computed using the residual of the element. The template argument should be equal to the size of the residual vector (element vector), i.e., the user should specify the size to match the exact vector size for the considered order of the shape functions.
