mesh for jets in tank, Gambit
I would like to simulate jets at the wall of a big tank. Could you send me link or sth which can help me to create the desirable mesh in Gambit?:confused: I have never done this before, so I don't know how to create the mesh in this case technically...
Please help me, it is quite urgent.
Prior to the mesh you need the geometry.
So you have to modelise the fluid domain and then you can start with the mesh.
In your case: create a brick, create a cylinder.
Move the cylinder and place one extremity of it, to one extremity of the brick.
Connect the brick's face with the cylinder's face (or split the brick's face with the cylinder's face).
Your model is ready.
Mesh the cylinder, mesh the brick.
Apply the right BC.
Of course, this is a trivial model and very simple geometry.
I have done the geometry and I have tried to mesh it. The only problem, that since jets are much smaller than the tank volume, I cannot mesh it.I get always the same error message:"small gaps...."
Could you send me a file or link, how to create mesh in volumes, with different and well defined densities?!
Thanks in advance. :D
If you followed my steps, you should have 2 separated volumes.
So you can mesh the cylinder first.
Mesh the top of the cylinder with the appropriate size.
Then mesh the volume of cylinder, also with an appropriate size.
Here your cylinder should be meshed.
Then mesh the tank, but you will have problem a the mesh transition between cylinder / tank, because of the difference between mesh sizes.
So you can apply an size function (option Meshed).
Pick the top of the cylinder as (meshed) source (should also belong to the tank) and the tank volume as attached volume.
Give appropriate growth rate and max size.
And Mesh the tank.
