SubscriberHello,
When using the "Use Q3D to solve the DC point" option, within a frequency sweep in the HFSS, the simulation returns the following error:
The simulation profile contains the following information:
The model consists of a PCB cutout and additional bodies: part of a housing, connector enclosure, a few wires (geometries united with the connector pins) and a copper bar connecting the housing to a reference plane:
The aforementioned reference plane is a "Perfect E" boundary assigned to the bottom face of the airbox:
There are multiple lumped ports and RLC boundary conditions defined between various copper lines/planes of the PCB:
My goal is to compute a scattering matrix of the PCB, to be then used in a transient analysis (utilizing the Nexxim solver in the Circuit environment). Hence I need to sweep the frequency from the DC up to the end of the bandwidth of interest (400 MHz):
The HFSS mesh is computed for the 400 MHz:

I haven't found any details regarding the error message. Could you please explain the meaning behind it?

Best regards,
Maciej
