Dear Foamers,

Is it possible to create baffles with cfMesh?

I am trying to mesh zero thickness walls within the domain. Using surfaceMeshRefinement, it is possible to refine around the wall, but when I check the mesh with checkMesh, the wall has zero faces. I have tried playing with 'keepCellsIntersectingBoundary' and 'keepCellsIntersectingPatchs', but in all cases I get zero faces on the wall patch.

In these slides, it seems that it is possible to create a baffle (see slide 4), but I can'e work it out.

My meshDict is as follows:

/*--------------------------------*- C++ -*----------------------------------*\

Hi Thomas,

Did you manage to figure out creating baffles? It would be interesting to know if you have succeeded. Thank you

Hi Krao,

Sadly not...

Hi,

Landed on this post while looking for how to do baffles in cfmesh, and then found out they had an example on their website using sails.

In case someone else lands on this post seeking the same answer, here is the link to the downloadable examples (then click on the sails picture to get a .zip):

https://cfmesh.com/download-examples/

Enjoy,

Ben

Hi,


I know it is way long since this subject is posted but the link is not working anymore. Would it be possible for you to share the files?


Tahnks.

Hi,

Unfortunately I changed job since and I don't think those were in the files I took with me. I will have a look, but if I don't come back to you it means I didn't find them.

You might want to send them (the cfmesh team) a mail to check if they are still available somewhere.

Best of luck!
