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?
