of the petsc/slepc installation I use. Also, diagonalization happens for smaller matrices.<br>

<br>
Use -eps_view_pre (it should view settings at the beginning of solve), or run a smaller case (settings should be the same).<br>
<br>
I will also need the other matrix, otherwise I cannot run EPS.<br>
<br>
Also, tell me which version are you using now, and which version worked before.<br>
