immersion antenna structure in oil on hfss

[kalthoum]

how can i do the immersion of my structure in liquide on hfss
do i have to assign the materiel of my boundaries box as a oil or what ?

 

[SLK001]

If you have a material definition of your oil, I don't see why using the radiation boundary box as your "container" wouldn't work. I've only used air and vacuum, so I have never tried this.

 

[kalthoum]

my problem is where i have to put oil in my structure if she's immersed ?

 

[SLK001]

Create a huge solid block that is the oil, one that encompasses the radiation boundary.

 

[kalthoum]

is that what you mean????

there is no problem if my port is immersed in oil

 

[SLK001]

That should work - the radiation boundary is a solid where you define the material.

 

[kalthoum]

ok i will try it

Dear SLK001,

I have another question for this. What are the parameters we have to define for the oil?

Only Dielectric const and conductivity enough for oil or any other parameters required

 

[SLK001]

You will need to define at least these properties:

Relative Permeability
Relative Permittivity
Bulk Conductivity
Dielectric Loss Tangent
Magnetic Loss Tangent

If any are frequency dependent, you will have to define that, too.
