Patching of sandbed for nonrectangular container
Dear all,
I am very new to Fluent and need some help. I am trying to simulate a fluidised sandbed. But my container is not a rectangular tank but a hemisherical one. it is semicircle shape in 2D model. To fill the tank half full with sand, I have to patch it.But when I use adaptregion, they ask me to specify x and y parameters. But the region I want does not have a fixed xy parameter.(it is not a rectangle due to the rounded edge,the y value changes). How can I solve this problem to fill the container half full? Please help if you can. Really thanks. 
Re: Patching of sandbed for nonrectangular contai
That's easy! Simply select rectangular box for region adaption and input opposite corners coordinates, something like this:
 first point, let's say lower right point: x>=x(max) y<=y(min)  second point, upper left point: x<=x(min) y=y(max) So, what I'm saying is that you do not need to match x,y values of grid, just define a rectangular box that will overlap the grid till y=y(max). Good luck, Razvan

Just to confirm : So you mean to say that I can just define a rectangular box even though it may be out of my 2D model as long as it covers the areas I want? Thanks Razvan!

Yes, that's exactly what I meant!
You're welcome, Razvan
