[deal.II] When Lame and nu are big number, the result is always zero.

Hi, I am the new one here, and recently I test a program solving elastic problem considering neumann boundary conditions. So I finish it on the basis of Step-17 by adding the neumann boundary conditions. I found that wen lame and mu are not large (i.e. equals to 1 by default), the solution

[deal.II] Re: Dealii Installtion fails because it uses the wrong MPI Version of the intel compiler. It uses debug_mt instead of release_mt.

Hi, recently, I have the same problem. When I complie the PETsc, it link the debug_mt/linmpi.so. So I think the reason is that Petsc is complied in Debugging, not Release. So I add the paras when configure the Petsc,--with-debugging=0 and give the opt-paras, COPTFLAG="-O2" CXXOPTFLAG="-O2"
