Draw a perforated plate
 
Hello everybody,

I am a fresh member to here. I have to model a perforated surface with CFX. I am going to draw it by ICEM CFX. Please let me to know do I want to create every single hole by using "Drill a Hole" tool?

I would be much thankful to your advices as I am a very fresh one to ICEM CFD.

Thanks.

Dano,
This can be easily handle when modeling it. Create the mesh file here and when you export it into CFX you can make the perforated section by using porous domain/domain interface. I think this is a crazy quiz asked by me when I know nothing about CFX. :)

Sorry I dont know about Fluent, but should be similar.

At the end you didn't mesh a perforate plate, but you replaced it with a porous zone, with same drop pressure as your perforated plate, right?

Whoa, cool pic!

Not sure about your mesh density in the regions of high shear near the hole lips though...;)

do you mean to coarse?

Yes, too course; looks like quite strong shear layers.

May I ask what it was for???

Cool, did you mesh it in gambit?

Once Simon told that they have implemented some gambit algorithms like Tgrid in ICEM (I think it was quad pave). Any how they are combining the strengths of different codes.

This is a filter with some thousands holes (diameter 0.8mm) for hydraulic system
Sure I put few cells in each hole, but I am handling with an old desktop (gambit 32bit), so I am very quick limited with hardware :)

Woow.. superb..!!!

I too think mesh density is not course.

But I want to know does anybody know how to do this one in ICEM CFD? I tried to do this but failed.
