[petsc-users] Mumps Error

[Hong Zhang]

Gabriele:
This time,
you get INFO(1)=-1, "An error occurred on processor INFO(2)=39",
according to mumps manual. Please ask mumps developer about
 INFO(1)=-1.
My guess is that your matrix might be numerical singular, causing
numerical factorization fail.

>>> I suspect it has something to do with the preconditioning or setup of the matrix I am trying to invert. The matrix becomes singular at energy = 0 eV, and is nearly singular for values close to that, but the code is failing on energies relatively far from that point. The affected energy interval is [-0.03095, 0.03095].
