[blockMesh] openfoam mesh for sphere

nafrin · October 24, 2019, 14:13

Hi all:
I am new in openfoam. I want to generate a sphere(hollow) with two inputs and two outputs. Anyone can help me? Thanks in advance!

Hello nafrin,
- what is your intention, your technical question, what should be simulated ?
- have you already created a 3D model?
- I strongly recommend to start with some simple tutorials, e.g. 'elbow' or 'TJunction'
- one can find a ton of useful tutorials for beginners on the internet, for example here:

Hi Nafrin,

For a simple geometry like a sphere, you can use blockMesh to generate the mesh. In this video you can see the blocking topology. It is an o-grid around the cube and then the surfaces/edges/points of the inner cube are projected on the sphere.

Best, Mikko

I want to create a reactor with 2inputs and 2 outputs. The sphere should be hollow and combustion will occur inside of the sphere. (I cannot attached the figure here. )
