Boundary condition error in hfss

Hello,

while checking boundary conditions hfss showing the error as " boundary RAD1 and boundary perfectE1 are overlap" please help me to solve this problem. i am attaching the hfss file please go through it.

Project7.rar

I do not have HFSS License at home so will be able to see your file on Monday but error is self explanatory as it clearly means that you have defined two boundaries in your model in a way that they are sharing same geometry. Just have a careful review of your model and see where you have defined these two boundaries and for sure you will be able to find the overlaping geometry try to resolve this issue

i could not find a solution to this problem, i searched it online i could not find the answer, please help me

Load HFSS file as this is not working with my system.
Lets see what and where is wrong in the project

please check the upload sir, if any problem occurs please let me know
hfss.rar

.rar extension is not working with me try to load it in some other format.
I am not able to open the file due to this extension issue if possible simply upload HFSS project file

please go through the below link sir

Thanks finally I got the file
Let me see what if I am able to debug the issue right now system is busy with one Simulation with CST

no problem sir, do it in your feee time

I am not expert on antennas so I do not know if I have done it correctly or not but at least now there is no boundary problem in the model.
I have just adjusted the position of your Air box in the model which was defined as Radiation Boundary and it was touching with your model where you have defined Perf E1 and Perf E2 boundaries resulting into warning message during validation see the attached pic for further explanation.
Also let me know if your issue is resolved

but when i searched about the airbox size it should be extended along radiating edges i.e top and bottom, not along the sides of the substrate

Here I am helpless to answer as my field is accelerator all I know is little HFSS so I found the overlap and suggested you one way out.
And this you always have to make sure that your boundaries do not overlap otherwise HFSS will give you warning
