Stability in CST MWS
Hi everybody,
i am simulating some antennas for milimeterwave application. Sometimes the simulation was aborted due to unstable state and the logfile suggests a smaller stability factor for the transient solver or a smaller PBA fill limit.
The simulation runs when i changed the stabily factor for timestep in the special settings to 0.7 (default was 1.0 ). Will this lead to an unaccurate S-Parameter result ? What about a smaller PBA fill limit ? I haven't tried it yet.
Or is there any other reason which could be the cause for the unstable state during the simulation ?
Thanks for your help.

abti
