**Creating Geometry in CADFEKO**

Create the model geometry using the CAD component, CADFEKO.**Launching the Solver**

Launch the Solver to calculate the results. No requests were added to this model since impedance and current information are calculated automatically for all voltage and current sources in the model.**Viewing the New Results**

Use the existing POSTFEKO session to display the new results.
