This means you are trying to add a number to your system matrix that is not finite. Do you have a division by zero in a coefficient or something? > while i changed my solver to UMFPAck solver another error was shown :(UMFPACK > is installed ) > ExcNeedsUMFPACK() No, that means deal is not correctly configured and compiled with umfpack. Make sure you configure with "--with-umfpack" and then check that ./configure and make completes successfully. -- Timo Heister http://www.math.tamu.edu/~heister/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
