Hi.I need help because I have faced a problem in simulation a design in HFSS.
I draw my design,define boundary conditions and excitations and I press Validation check button.It bears error:At least one material assignment should have solve inside set.I don't understand what it says.please help me.
:cry:
 

Hello

This is mostly likely if you have solid boundaries and no radiation box defined.have you defined a radiation box for your design.try it and post your response

Thank you very much for response.I will try it and post the result.
May I ask another question?I want to design a cavity excited by a probe,I first draw a copper cylinder,subtract a vacuum with smaller dimensions from copper cylinder and then I draw a cylindrical probe inside the cavity where the vacuum has been subtracted.why does HFSS say that objects intersect?How can I dray this cavity with a probe in it?
 

when you draw the cavity and the probe.You have to do a simple thing if they are intersecting. go to toolbar---HFSS---design settings and check the box where it says" enable material override" problem should be solved
