Hello

I have strange bug in surfaceToPatch utility.

I have polyMesh with patch called "wall".

I have created faceSet of wall called "wall" even though it is not necessary.

I have stl file called "in.stl"

I have to create new polyPatch called "in" using stl file where it matches tolerence of 0.001.

So i use surfaceToPatch utility :

I use OpenFOAM v1.6.x

Here is the bug report:

[bruce@cfd4 patchCheck]$ surfaceToPatch in.stl -faceSet wall

Can anyone help me to fix the problem?

Kind Regards

Do you have a small testcase you can post or send (m.janssens, domain opencfd.co.uk)

Hello Mattijs

I have posted a very small test case that reflects my problem.

Thanks and Best Regards

I've pushed some changes to 1.6.x. If I use attached controlDict (moved the minX? patch to coincide with the inlet.stl) it works. Please let me know if there any more problems with it.

Thanks,

Mattijs

Hello Mattijs

Thanks, it works
