Hello OF-Community,

I am looking for a possibility to display eMesh-Files (e.g. created by surfaceFeatureExtract) in order to check their real content.

Is there any utility or the like?

Thanks in advance.

Cheers
MasterCooler

Hi,
you can import them in paraview.

Dear val46,

thanks for the quick reply.

I thaught that as well but I didn't work. Firstly I cannot open the eMesh file directly and even if I use the option writeVTK the generated additional file (format .extendedFeatureEdgeMesh) cannot be opened by paraView, isn't it?

I have seen that there is the option "writeObj" which also several obj files for. Amongst others there is a file "..._edgeMesh.obj" which can be opened in paraView and contains all edges. Is the content of "..._edgeMesh.obj" surely comparable with the content of the eMesh file generated in .../constant/triSurface?

Regards
Ben

Yes, I think so.

Greetings to all!

You can use:
Code:
surfaceFeatureConvert constant/triSurface/file.eMesh features.obj
to convert "eMesh" to "obj". You can also use a random extension name to see which extensions are accepted.

Best regards,
Bruno

Good morning Bruno,

I have just tested your recommendation which would completely solve my problem. Unfortunable I got the following error
Code:

With the same file it was possible to write out the obj files while running the surfaceExtract command. Any idea what could go wrong?

Thanks in advance for your reply.

Cheers

Hi Ben,

Open the file "constant/triSurface/geo.eMesh" with a text editor and check if there is anything out of place, as the output indicates!
Or if you can, attach the file "geo.eMesh" on your next post so we can see what might be wrong there!

Best regards,
Bruno
