Failed to evaluate AWE expression. Not all parameter steps returned.

Hello,
I am getting the error "Failed to evaluate AWE expression. Not all parameter steps returned." when running an Adaptive Frequency Sweep study for an Electromagnetic Waves, Frequency Domain physics. The model is a waveguide antenna with two lumped ports in a coaxial configuration. I run a "Frequency Domain Study" and it converges with no problem. But when I run "Adaptive Frequency Sweep" from 3 GHz to 4 GHz, in order to plot S11 parameters vs frequency, solution does not converge. I tried both Direct solving with MUMPs and Sugessted Iterative Solver, but they both did not converge. I am confused why this is the case since the "Frequency Domain" problem converges without a problem. Is it possible adaptive frequency sweep doesn't work properly when you have more than one excited lumped port?
I can't attach my file as it is too large but I have attached a screen shot.
Any information would be greatly appreciated.

Is it possible this could be memory problems?

Hi Sam, If you have figured out solution for this problem, please let us know. I have been going through the exact same issue and not being able to figure it out.
