Yes, it is intended to compute these quantities for you. Let me know if it
does
Thanks, Matt.
It seems DMPlexComputeCellGeometryFEM works well with the quadrature
points to deliver Jacobian and inverse one.
Will it be a good choice ?
Have a good night.
Thanks,

Dear Petsc developers,
I am learning *PetscDTSimplexQuadrature *and plan to use it.
I found that, in the biunit simplex (tetra),
(-1,-1,-1),(1,-1,-1),(-1,1,-1),(-1,-1,1),
degree 1: npoints 4, the sum of weights = 4/3(the volume of this simplex)
degree 2 : npoints 8;
For my previous experience, I
