Hi,

I tried to merge two meshes together using mergeMeshes util, but, failed. Is this a bug, or did I do something wrong? I did not have the same problem with OF-1.3.

Error Messages attached.

Hi,

OK, I found how to use mergeMeshes now.

Before performing mergeMeshes, in boundary of the master case, I need to add the patchnames (from the second case) with nFaces 0 - some kind of place holder. Then, mergeMeshes was successful.

Hi Pei,
I am trying to do the same without success. I followed your solution and added a patch in the boundary of the master mesh which contains the interfacing patch from the slave mesh, i.e.

Mesh_rest_dom_front
{
type patch;
nFaces 0;
startFace 17860;
}

This did not work (Note, I incremented the number of patches at the top of the boundary file). Can you please provide more details of the changes you made to the master boundary file.
Thanks
Anant

Hi, Anant,

Could you please either email me your case files or post the error messages? I recalled that, all I need to do is to add the patches (in the slave mesh) to the master mesh prior to mergeMeshes.

Did you check the meshes that you are trying to merge "before" merging? Are the meshes checked out fine (checkMesh . case) prior to merging?
