hfss lack of precision
[error] Adaptive solution setup, process abc3d : Failed to solve the problem due to lack of precision. The likely cause is that the frequency is too low.
The error will be gone at higher frequencies such as 10 GHz, but frequency band of my interest is 10 MHz

According to the manual, wave ports have to be specified to object faces which
are exposed to the background or outer.
Probably you have to use lumped ports if you want to use a port within the 3D model
driven modal driven terminal
As explained in help:
driven terminal gives solutions in terms of voltages and current
while
driven modal uses power
Added after 19 minutes:
Specifically, Driven modal: S matrix is solved in terms of powers; Driven terminal:
S matrix is solved based on voltages...
I am new to hfss software, I would like to simulate the electrical properties such as characteristic impedance vs. frequency of a novel grounded CPW structure embedded in a 50 ohm coaxial line.
Could someone give me suggestions about how to start?
Thanks a lot!
