solver run aborted cst
Is there any magic step when using CST MWS eigenmode solver??
My simulation is just to find eigenmode frequencies of a tungsten woodpile EBG structure. I ran it on a 12G ram computer and just couldn't get it through! Always error info comes out like this :"Maximum iteration number reached. Simulation aborted."
I followed every possible step I think it should take:
1. Set units
2. Set background material (normal -> air)
3. Define structure (set up my unit cell and use periodic boundary conditions on x, y and z directions)
4. Set frequency range (I first used 200 - 650 GHz, doesnt work, then I tried fmin=2GHz and only calculate 3 modes, still aborted)
5. Set boundary conditions
6. Start eigenmode solver
Help needed! Am I doing everything right?

And BTW I choosed JKM algorithum already, which according to CST Help should be able to deal with lossy materials including Tungsten.

Memory should not be a problem since I can run the same model through on HFSS and HFSS is usually more memory consuming than CST.
