Hello guys,
I am still trying to compile my old multigrid code. But i get so many
warning, one of those warning is like this:
MsFEM_poisson2D_DMDA.c: In function ‘int main(int, char**)’:

^~~~~~~~~~~~~~~~~~~~~

Can you guys help me to fix or solve this warning in order to get the code
run smoothly. Please help
