StitchMesh
 
Hi friends,
I have imported meshes from fluent to OpenFoam, I have merged my meshes I am not able to stitch meshes, I have gone through quite a few number of threads but did not get correct idea can anyone please help me regarding this,
http://www.cfd-online.com/Forums/ope...1-5-1-6-a.html
In the above link there are some correction patches , but even after compiling these corrected patches I am able to see 2 diffrent meshes,
so can anyone help me,
Will be easy If I send the mesh files,
Thanks in advance,

What do you mean with "see 2 different meshes" and what does stitchMesh say? BTW: you're sure that you looked at the stitchedMesh (which is not in the constant-directory but in the next timestep).

Firstly thanks Bernhard, I meant I am able to see diffrent domain in post processing, I basically meant the flow is not possible through merged mesh, its not passing the interface of 2 meshes, so i assumed stitching is not done in correct way,

and I could not understand the stitching of meshes after studying pleanty of post,

I also saw in all time steps in post processing but also the mesh was same.

It only merges but stitching is Difficult.

The ultimate Test is checkMesh. If it says that the mesh consists of two regions then it is so. Again: without the error message (or other message) that stitchMesh gives you (and the command line) nobody here can help you

Hallo, Pramod
May you show me how to compile these
these corrected patches in Change in triangle::intersection breaks stitchMesh in 1.5 and 1.6 ?

I really can not find where i should locate these patches.

Thank you very much!!!
