Add Solution Setup and Frequency Sweep

Solution Setup

We need to define our solution setup with parameters such as solution frequency, maximum number of passes, and convergence criteria. Right-click on 'Analysis' in the Project Manager window and select 'Add Solution Setup...'.

In the window that appears, change the Solution Frequency to the design frequency (2.5 GHz in this case). Change the Maximum Number of Passes to 20 and the Maximum Delta S to 0.01.

In the 'Options' tab, change the Minimum Converged Passes to 2. Click OK to close this window. The simulation will continue to run until the convergence criteria is met or until the Maximum Number of Passes is reached, whichever comes first. The convergence criteria is that the Maximum Delta S needs to be below 0.01 for 2 consecutive passes. Before we run the simulation, we need to setup a frequency sweep.

Frequency Sweep

Right-click on the solution setup you just created (Setup1) in the Project Manager window and select 'Add Frequency Sweep...'

In the window that appears, change the start and stop frequencies to 1 GHz and 5 GHz, respectively. Change the step size to 0.001 GHz. For now you may leave the Sweep Type as 'Fast', however 'Interpolating' and 'Discrete' can be more precise at the expense of longer simulation time. Click OK to close this window.
