[mesh manipulation] createPatch: dumped objects

Perfectdark · April 18, 2016, 07:20

Hi,

I'm wondering why createPatches always makes *.obj files in the case directory. What are they worth for and can I avoid them to be created?

Thanks in advance!

Hi,

So far in my usage, I have not had createPatch dump out any *.obj files. Are you running your OF with any particular debug switches enabled?

Cheers,

Not that I know of. Where do you turn on this kind of switches?

EDIT: I forgot to mention: I'm using OF 2.3.1

Hi,

The only thing remotely relevant that I could find among the DebugSwitches was one called "obj". But I really have no idea either if that is the actual one.
You could set it to zero in the controlDict, thereby providing an override and see if it solves your problem?

where can I turn it on or off, this switch?

Edit: found it, just trying...

Edit2: makes no differnce whether turnd on or off.

Hi,

Hmmm. Your problem is definitely something that I haven't encountered either in 2.1 or 2.3 or 2.4.

Maybe it is a bug that is specific to 2.3.1? OF 2.3.0 that I used didn't have that issue.

On a related note, what is the exact command that you use (with flags etc)?

Cheers,

I just run "createPatch -overwrite" with nothing else

hi,

Got it! Your patch is of type "cyclic" isn't it?

If so, then it seems to be part of the createPatch process to write out .obj files. Look at the source code for createPatch and you will see what I mean (https://github.com/OpenFOAM/OpenFOAM.../createPatch.C)

Hope this clarifies.

Cheers,

You're right, I just figured it out myself. But I didn't found out yet for what this is worth. My case runs also without them, so I'd say this is just some sort of additional output to analyse the interface.
