Indoor airflow simulation result

#1

Hello I am new to the butterfly simulation and I was trying the simulation for indoor airflow.
I successfully tested the example file so I modify the file to my case, but the result comes out strange though.
Any suggestions?

By the way, the mesh that created is really strange but I think the boundary setting is ok though…?

Hi,@endison8
The rhino geometry is missed in your grasshooper definition . Please upload it for further discussion.

Hi, sorry for the late reply, here is the file:

Hi,@endison8
There are serval bug for your grasshooper definition.

  1. refine will should be more higher to retain the shape of geomertry.
  2. The X/Y/Z mesh count should be more.

    3.the surface level should equal to max refine level.

    Here is the screenshot of velocity in Rhino.

    And I suggest you to use paraview for visualization.

Thank you so much for the reply, sorry but I have a few questions though…

  1. may I ask what does the refine level mean? Why should I set to (4,4) instead of the example file (2,2)?
  2. Number 3: the surface level should equal to max refine level. I’m not sure which of the screen shot setting made the surface level equal to the max refine level?

Hi,@endison8

The value of refine level depends on the details of the geometry.East and west windows are thin and long. You should set a grid for east and west windows,so you should set high level for them.

The refine levle I set is (4,6).So the surface level is 6.
