Hello all,
I am currently using CST Microwave Studio to simulate my project dealing with waveguide.
The problem is we are simulating the problem in a wide frequency range (2-22GHz). There is a warning "At least one propagating modes at port 1 is not considered in time domain calculation. It might be better to increase the number of modes at port x".
I have tried increasing the number of modes because obviously over that frequency range there is quite number of modes propagating. However that didn't give correct result. I can say that because I have an empirical data that I can compare to.
This has trigerred two questions. (1) What is the meaning of the error and what could be done to solve the it.
(2) Can I simulate wide frequency range with several modes(2-22GHz) in waveguides just by leaving the default settings?
Thanks heaps.
