Solving problem on subdomain
I want to compute an incompressible flow profile round a sphere in a box (see attached PNG).
The mesh is generated with ICEM, stored in Fluent format, and converted to OF with fluent3DMeshToFoam without any problems. Most important converter output:
I have not yet tried to run a simulation (with simpleFoam), but I have a few general questions in advance:
How does OF treat such multidomain problems in general? Will it treat the two cellZones as one, or will it just ignore the second, or what else?
Or how can I tell OF to ignore the cells inside inside the sphere?
I'd appreciate any information on that!
I would remove the cells inside the sphere. You can do this defining a cellSet and deleting the elements belonging to it. Take a look at cellSet/setSet tools.
thanks for your reply.
After fixing the boundary conditions at inlet and outlet, I now got simpleFoam to compute a solution. It works, but the solver includes the cells inside the sphere. Since these are completely surrounded by walls, nothing happens there. But I should definitely get rid of the cells for larger realistic problems...
I did some googling on cellSet and setSet, but didn't really come up with useful documentation. Am I missing any important docu site? Or maybe could anyone shed some light on how to use these tools?
