[petsc-users] Question on re-coding ex29

[Alan Wei]

Dear John,
    Thanks for your quick reply. I think the error message says that the
BCType has some problem. However, it is originally there and I have not
changed it at all. Is that because I define it in ComputeRHS again and let
ex29.c include ComputeRHS.h so the BCtype is duplicated?

thanks,
Alan
