Re: [deal.II] Extracting Shape Laplacian

Thanks, I did try looking at the documentation for FEValuesViews::Vector < dim, spacedim >::hessian(const unsigned int shape_function, const unsigned int q_point) before coming here, and all it provides is "Return

[deal.II] Extracting Shape Laplacian

Hello all, I am working on implementing some stabilization methods for the Navier-Stokes equations, these techniques often require the use of the laplacian of the shape functions. I know I get the hessian of the k'th shape function at quadratue point q via the following Tensor<3, dim> hessian
