About CST microwave

Dear Colleques;
I have a problem with simulating in CST such that:
error occurs while simulation : "error during construction of pre-conditioner. not enough memory"
what would you suggest me?
Could "pre-conditioner" statement be related with boundary consitions?
Thank you so much for your help
Regards

Hi,
try decrease mesh cells or use set in boundary conditions symetry planes.

Thank you,
also I couldn't find any hint for floquet boundaries and this kind of port?
how can we find from CST ?
regards

Hi,
Bloch-Floquet boundaries can also be set in the boundary conditions menu, where you can chose between electric&magnetic walls, open, or periodic boundary conditions.

Hi,
one more thing I needed to ask.
I have checked from B.C. menu but I couldn't find..I use CST 2008, could there be an new edition issue?
Thanks for your help
