Hi!
I have done a mesh with the match control option, and it works well, but when I try to make the zones periodic in Fluent it gives me the same message of your first post. Regards EDIT: Sorry, the message is the one that appears in the first post of discussion, not in your post. Thanks in advance! |

I have remeshed the geometry and I don't have the problem right now, but I will try this solution when the message appears again. Thank you very much! Regards |
Normally there could two reason for this error. First check the origin of rotation.
So how do we check, open the design in design modeler then use point entity to check the centre of rotation coordinate. u can even draw on the surface of your model and find the centre of rotation. (anyway works). if its rotating along z axis then get the x and y coordinate and place it in fleunt>cell zone condition> rotation axis origin. if it does work then maybe its due to different number of cell on the face of the two surface. It a non conformal periodic.(https://www.sharcnet.ca/Software/Flu...ug/node186.htm) you have change the type of B.c from wall to interface then use Mesh Interface where you select the surfaces, check the periodic B.C set the angel offset and create periodic. |
