Patching of sandbed for non-rectangular 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 adapt-region, 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.

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
