Hello everyone. I am new to openFOAM. I managed to blockmesh a cylinder using the m4 file in this link.
https://www.ehsanmadadi.com/cylinder-mesh/ Then I want to create a second inlet on the wall as shown in the image attached. Can anyone please tell me how to write this in blockmesh. pipe.JPG |

Very probably there exist some ways to handle this.
If I had to manage this case, I would generate a regular cylinder with a slightly different formulation for the wall speed (which is zero in most places at the wall). It is possible to use for a surface a nonuniform velocity in the form Code:
type fixedValue; value nonuniform List<vector> {elements} ( (ux0 uy0 uz0) (ux1 uy1 uz1) : )

Hi,
If you are using OF 5, then you could try their new "project" feature: https://cfd.direct/openfoam/user-guide/blockmesh/ (Look for section 5.3.3) Cheers, Antimony |
