ANSYS Geometry with zero thickness walls
 
Hello everyone,

I am having trouble making the design of my simulation.
I have a cubic body and at the back there are plates mounted at an angle to reduce the drag at the back. I already did simulations without the plates.
I want to model these plates as plates with zero thickness, but is this possible?
I am able to subtract the cubic body from the air domain, but if I make the plates surface bodies I am not able to subtract it from the air domain, which makes sense.
Now I only subtracted the body from the air domain and created a body where the four sides are resembling the plates. But I am not able to assign a named selection to it, so I can make it a wall.
Can anybody help me?

Well, I'm with the some problem here :/

The default thickness at Mechanical is setted as 1000mm and I'm working with "Plane Stress".

Maybe you don't need those plates, but you need to slice your domain to get corresponding surfaces (walls).

Please, clarify your question.

Hi,

I also have similar issue,

how to generate zero thickness wall in Ansys Flunet meshing.

I have made the zero thickness wall, but it is not counting in simulation ?

Needs some helps...

Regards,
Prasanna.
