Issues With CST Eigenmode Solvers

Has anyone been using the Eigenmode solvers in CST MWS 2011? Successfully?
I wanted to check out the new solver that uses a tetrahedral mesh, so I simulated a helical resonator with it, thinking a helix would be a good structure to test tetrahedral meshing.
After about 30 minutes of spinning its wheels, the application used up my 4 GB of RAM and self-aborted.
What a joke.
Then I tried the same problem with the "AKS" solver (hexahedral mesh). With only low to moderate memory usage, I got a quick solution to the problem in only a few minutes. Unfortunately though, the frequency of the lowest order mode was off by 2 orders of magnitude.
Then, without changing anything, I switched to the "JDM" solver, and finally, I got what looks like the correct solution.
Anyone else have a similar experience?

- CST Postprocessing of multiple S-parameters (single frequency parameter extraction)
- Shielding Simulation in CST
- Illegal usage of S-Matrix, No impedance found error in cst
- Line impedance in CST
- CST dual polarized H-slot antenna is very well matched but has poor total efficiency
- CST Matlab Interface, Export Far Field Result Automatically
