Problem DescriptionGetting StartedCreate the 3D modelAnalysis SetupPlot S-parameters vs. FrequencyCreate TraceThere are multiple ways to specify the position and dimensions of a trace, orany shape in generalOne way is to enter the information in the coordinate entry fields.Variables are not allowed in the coordinate entry fields.Another way is to draw an arbitrary box first and modify its position anddimensions with variables.Using variables is encouraged as it is easier for changes to be made onthe designs.Here, we first create a box in the 3D modeler window and then redefineits position and dimensions with variables.Tianjian LuECE 546: ANSYS HFSS Tutorial
