Thanks for your quick response, Praveen. Unfortunately, your solution
didn't work for me because I don't have a "configure_50_hdf5.cmake" file
(or any similarly named file) in my deal.II folder in spack. It did point
me in the right direction and I have now been able to compile and run all
my deal.
Dear all,
my objective is to do an 1d-approximation
F(x) = N_i(x) P_i
where N_i are cubic B-spline basis functions and P_i known nodal values
(control points).
To assemble my linear system, I have to compute the first and second
derivatives of F at the quadrature points of the triangulation.
