[petsc-users] eigensolution error with slepc

It turns out that the matrices that I sent you was from a load step before the one that failed. 

I am calling eps_solve once for each load step, and I get the error at the 14th load step. So, the matrices that I sent were from step 13. 

The eigenvalues you got match the 1/lambda that I get from my code at load step 13. 

I will try to output the offending matrices and share those with you. 

Regards,
Manav
