... Symmetries have been defined. This is currently not supported by the PIC solver. , в чем может быть проблема?
Do you have symmetry planes in your project (look in the "Boundaries")?
If you do, try to remove them.
My experience of simulating multipaction with CST says that CST is not very accurate for that. At least that was the case about two years ago. I hope, they improved since then.
