Hello, I'm using Petsc 2.3.1 in Debian (updated by apt-get) and I don't find information in the web and in the troubleshooting section about this error message:
> [0]PETSC ERROR: MatMatMult() line 6543 in src/mat/interface/matrix.c > [0]PETSC ERROR: Nonconforming object sizes! > [0]PETSC ERROR: fill=-2 must be > 0.0! Maybe you know what does it mean because I've tried a lot of thing in my code to solve this problem :-((( My Matrices have the same dimension. regards,\j -- Jordi Marc?-Nogu? Dept.
