Dear PETSc developers, I have a code that uses PETSc to solve the elasticity problem with the finite element discretization written by myself. I found there is a part called "PetscTabulation" that stores the basis functions. I would like to inquire about this part that can I use this part for achieving high order element? In detail, how does the basis functions be evaluated and in which file can I find the basis functions? I'm thinking about using PetscTabulation and PetscQuadrature to achieve a high order element. Is this doable?
The next question is can I output a vector that the unknown is defined on each element (not point) using VecView? I think this question relates to the PetscViewer for VTK. Thanks in advance for your help! Best Regards, Jerry
