Hi,

I created a quarter of a cylinder (the cross section is a quarter of a circle) using blockMesh. The problem I am solving is true 3D, so, I would like to generate the mesh of the complete cylinder. Since this is symmetrical in X-plane and in Y-plane, how can I generate the mesh of the whole cylinder using "mirror" technique?

Thanks Eugene!

I did try mirrorMesh and got strange results. The geometry was mirrored, but, mesh were messed up. It looks like mirrorMesh requirs mirrorMeshDict. I set the point to (0 0 0) and vectorToNormal to (-1 0 0). The following command was used:
mirrorMesh . casename

I probably did something wrong.

Hi Eugene,

I tried mirrorMesh again. I moved the base point to an node point inside the domain, and it worked perfectly. Previously, I simply picked one corner point of the geometry.

Also, after mirrorMesh, it looks like there is no need to run stitchMesh to remove duplicate nodes on the symmetry plane - nice!

Hi Nikhil,

A sample dictonary can be found under:

~/OpenFOAM/OpenFOAM-1.4.1/applications/utilities/mesh/manipulation/mirrorMesh

Btw.: Please refrain from double postings in the future. In fact it makes it more unlikely that your post is answered.
This has been discussed recently:

Best regards

Hi Nikhil

Please check out this directory

OpenFOAM/OpenFOAM-1.4.1/applications/utilities/mesh/manipulation/mirrorMesh

For future searches please use beautiful features of LINUX such as locate or find . Other appraoch is to please familiarize yourself with the following OpenFOAM folders:

/src
/applications/solvers
/applications/utilities

Hope that will help.

With Best Regards
Jaswi
