What is the difference between simulation and model frequency?
The simulation frequency or frequencies are the frequencies at which the problem will be simulated. The simulation frequencies are set under the Simulation Settings tab in SuperNEC.The model frequencies can be thought of as the segmentation frequency. In other words this is the frequency which determines the length of the segments. This is set at the bottom left of the SuperNEC GUI. This should be set to the highest frequency at which you will be simulating the structure.
