Hi,
I am working on 3D Navier Stokes equations. I use Newton’s method. We met an error when executing ChangeNumbering from Freefem to PETSc:
Assertion fail : (ptIn->N() == ptA->_A->getDof())
line :2946, in file PETSc-code.hpp
I am not sure what happened here. Could you help me out? I attach the code here.
