I have set upper domain as AIR (white color-up) and dielectric (gray color) domain as glass by PRPS. But I can't set electric permittivity for AIR and dielectric material. I have used INITIAL PATCH to set two separate permittivity. But in glass INITIAL PATCH can't set permittivity. Can anyone give me some suggestions? ]]> Phoenics mukut http://www.cfd-online.com/Forums/phoenics/79825-how-set-electric-permittivity-plasma-actuator-induce-flow-simulation.html Making of 4 quadrant of windcatcher. http://www.cfd-online.com/Forums/phoenics/79348-making-4-quadrant-windcatcher.html Fri, 20 Aug 2010 15:51:27 GMT Dear All,
I need help in making a model of 'windcatcher' in Phoenics 2009.
Those who are not aware of what 'windcatcher' is, please see the attached image. A windcatcher has 4 quadrant winthin its square shape and air flows in and out each quadrant independent of each other.

My problem is when I'm trying to model it in Phoenics 2009, I'm experiencing that I can't rotate any plate object in the program. I've tried with the 'shapemaker' and still unable to do that.

I've imported .stl, .dxf and .3ds files and they appeared, but the air flows through from one to another, with those imported geometry (even though I assigned them as blockage material means the four quadrant is not working, they are behaving like one box.) I want the air that 'flows in' should not mix with what is 'flowing out'. You can see in the attached image that air is mixing from one quadrant to another, which I dont want.

Can anyone help me about how I can make a shape as in the image attached here? Many thanks in advance for your help.
