Re: [deal.II] Re: error while using refine_and_coarsen_fixed_number
Dear Bruno, I agree to you. But I am dealing with the one dimensional rod theory and I want to understand more complicated deformation modes, so I go for spacedim 3.

Thanks for the reply. By saying spacedim 3, I mean that the rod (being one dimensional) can deform in the three dimensional space.

Re: [deal.II] Trouble getting UMFPACK to work
Dear Jean-Paul,
Yes, I was able to solve that problem. I installed LAPACK using the
command and later I compiled the entire deal.II library. Thanks for the
help.

Darius Barreto.
