Hi, Sorry for the very late response... I attached the slepc_variables and slepcconf files, I couldn't find slepc_common_variables. Where exactly should that be? Even using Arpack, I still have issues. I have a generalized condensed eigenvalue problem, and I'm interested in the smallest eige

Are we somehow hijacking SLEPc in such a way as to prevent it from reading it's own options? Because you can set the solver type for SLEPc from the command line (in this case would be -eps_type arpack). If we are, we need to fix that. On Wed, Apr 30, 2014 at 3:30 PM, Roy Stogner wrote: > > On

Hello, Now I should have slepc correctly installed with arpack. But still it looks like I cannot use arpack in libmesh, since in the file slepc_eigen_solver.C the arpack lines are commented out: // case ARPACK: // ierr = EPSSetType (_eps, (char*) EPSARPACK); LIBMESH_CHKERRABORT(ierr); return;
