Hi Timo, Thanks for you suggestion.
I reconfigured deal.II with umfpack and lapack. Now I can get the results from the step-29.
I did not built lapack in deal.II before, and I think that is the reason of error.

Dear Xiao Liu,ExcNeedsUMFPACK() I thought I had built deal ii with umfpack and BLAS.This exception indeed means, that deal.II is not configured correctly with umfpack. Can you please check again that you "configure"d with "--with-umfpack" successfully and that you (re)compiled deal.II and the example after doing that? Best, Timo
