i am new to hfss design environment.i want to know how to define lumped capacitance (lumped rlc boundary condition). suppose i want to place it in the gap of a grounded cpw structure.
Actually i'm new to this forum; so the reply may be late
To assign a Lumped RLC,
* create a sheet, where you assign this lumped element (you need to execute "detach faces" under 3d modeler, surfaces)
* right click on the sheet you created:
-Assign boundary > Lumped RLC
* in the dialog box, enter the r, l, c values you want.
* do not forget to define the line, which indicates the direction of the current flow.
ansoft products can be linked to each other.
the best way for simulating lumped elements and em structures is using "Hfss" with "Ansoft Designer".
