Hello everyone, I ran an example of PETSc on Windows, load “PETSc” macro dimension()2// EOM include “macro_ddm.idp” macro grad(u)[dx(u), dy(u)]// EOM load “Element_P3” func Pk = P3; border upper(t=0, pi) { x=cos(t); y=sin(t); label=1; } border lower(t=pi, 2*pi) { x=cos(t); y=sin(t); label…

You need to use FreeFem++-mpi, not FreeFem++, see, e.g., Hydrodynamic Stability Implementation in FreeFEM - #4 by prj.
