moving Tx and Rx positions with linear steps to make scattering measurements on materials.

Hi all 

I have modeled a multi layer material structure in HFSS to measure scattering response on the structure ( model includes multi layer structure + 2 antennas) . I have used Tx, Rx with an offset. I want to move both antennas across the axis to record the S11 response at each location. is there a way to do it automatically . simply, i want to move the antenna and source automatically. 

for exmple:  tx and rx must  start from  0,0,0, and finish at 0,0,100  at  20 steps.  at each steps response should be recorded. 


please help.

Hi Rakeeb,


Add a 'move' command (select object(s) then 'Edit > Arrange > Move') to each object/port you want to move and define the parameters of the move command (x,y,z) with variables. Test it's working properly by manually changing the variable(s) under 'HFSS >  Design Properties...' Then right click on the 'Optimetrics' listing in the tree and select 'Add > Parametric'. Here you can define the variables you want to sweep in stepped increments and the results/expressions you'd like to evaluate for each case.
