Solution Repeatability

Hi,
I'm running an eigenfrequency analysis with a plane stress model. The modal frequencies seem to vary somewhat wildly every time I run the solver (changing neither the model nor any parameters between runs). Is there any way to assure more repeatable solutions. I am more interested in repeatability than accuracy.
Thanks!

Some solver settings are designed for iterative solving resuming calculation and so forth ,,..
"lack of repeatibility" is a feature then..
for example check the initial solurtion in the solver settings if it is set for previous solution [anything but expression] then you will get a different case every time you run the solver without changing anything... there might be other settings that create the same effect.. read carefully the solver section of the doc and make sure you understand every single setting there [ even the default one]
