[petsc-users] what kind of stuffs I forget to free?

[Fande Kong]

Thanks, Jed,

I tried valgrind, but it could not catch any noises. I used these
options:   mpirun -n 8 valgrind --tool=memcheck -q --num-callers=20
--log-file=valgrind.log.%p   ./nonlinearElasticity3d  -malloc off .

I think I forget freeing something or petsc does.
