The size of the lumped RLC components in Ansys HFSS significantly affects simulation results, particularly in terms of resistance and impedance matching. Users must define the physical dimensions of resistors, inductors, and capacitors accurately to ensure correct performance. The component values are inherently linked to the area of the lumped elements, meaning that adjustments to size will directly influence the simulation outcomes. Therefore, it is crucial to set the sheet size appropriately to reflect the actual physical components used in manufacturing.

Yes, I set lumped RLC on 2D sheet in HFSS. And when its size changes, the result changes too. So I want to know how can I set a resistor/inductor/capacitor in HFSS without the influence of sheet size.Baluncore said:I do not use Ansys HFSS, but I would question the 2D? size of the Lumped RLC in wavelengths.
If you were using Lumped RLC to define a resistance, then size and the resultant resistance would change the termination and impedance matching.
I do not believe you can. Where the lump has properties specified per unit area, the component value will be dependent on the area. You will need to define the component shape and size as the area of the physical component to be used later in manufacture, and then give it the appropriate properties to get the value required.Melon said:So I want to know how can I set a resistor/inductor/capacitor in HFSS without the influence of sheet size.
