Yes. The eigenvalue calculation is performed using Libmesh/slepc interface. > I won't say this is impossible but it would be very difficult (and the > result might be non-unique) even if you could do it.

If not, I might then just do the eigenvalue/transient in one calculation to avoid this pitfall. Thanks for the help John !
