From Star To OpenFOAM

Hello,
I got Star model files (.ccmp .ccmg .mdl).
How can convert it in OF format? I had not the .vtr file.
I tried with "starToFoam" but I think I'm wronging something...
Can anyone help me?
Thanks in advance

Andrea

"starToFoam" converts vrt/cel/bnd files that use pro-STAR v3.x format.

"star4ToFoam" converts vrt/cel/bnd files that use pro-STAR v4.x format.

"ccm26ToFoam" converts ccm geometry files (ccmg) and is normally found under applications/utilities/mesh/conversion/Optional. Be aware that it may not handle separate calculation domains (eg, fluid/solid/porosity) very nicely though. If you experience any strange problems, you might also try simply saving the mdl as ASCII to get the vrt/cel/bnd files and use star2ToFoam.

Hi Mark,
Thank you very much for your help,

First, I tried to compile "ccm26ToFoam" with ./Allwmake but It seems don't work fine

Quote:

+ cd /usr/software/OpenFOAM/CentOS-5.3_x86-64/1.6.x/ThirdParty-1.6.x
+ ./AllwmakeLibccmio
+ packageDir=libccmio-2.6.1
+ '[' '!' -d libccmio-2.6.1 ']'
+ '[' -d libccmio-2.6.1 -a '!' -d libccmio-2.6.1/Make ']'
+ cp -r wmakeFiles/libccmio/Make libccmio-2.6.1/Make
cp: cannot stat `wmakeFiles/libccmio/Make': No such file or directory
+ '[' -d libccmio-2.6.1/Make ']'
+ '[' -e /usr/software/OpenFOAM/CentOS-5.3_x86-64/1.6.x/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libccmio.so ']'

If I try to run wmake into ccm26ToFoam directory I obtain:

Second, How can I save the mdl in ASCII? I can't open it with gedit. Do I need to make it by Star?

Thanks

I don't know why the Make files/options are missing (on your installation or in general). I've attached what I have.

Open pro-STAR, use "Save As Coded".

Greetings,

The Make files are missing since ThirdParty 1.5. They are also available here.
And it has also been reported here, although not clearly has being ccm26ToFoam, just libccmio.

Best regards,
Bruno

Hi,
Where shall I copy the wmakeFiles? I copied it into OpenFOAM-1.6.x but the ccm26ToFoam still don't work.
Have I to modify "files" and "options"?

Thanks
Andrea

OK,
I copied it into ThirdParty-1.6.x and now it's running
Thank you very much

Regards

Hi,
I have other questions about Star VS OF (sorry but I don't know Star).
1) I translated the .ccmg file in OF with ccm26ToFoam and it's quite ok. I have strange cellZones into my shell. Can I delete them?
2) My .mdl come from Star CCM+. Can I save it "as coded" with Star CCM+ to get the vrt/cel/bnd files?
3) I tried to re-translate the OF mesh with foamToStar and OF created the vrt/cel/bnd files. Can I open them with Star CCM+? Is it possible to translate the OF mesh in .nas (or .stl) format?

Thanks

Andrea

Another question
4) Can I use the .ccmp file in paraview?

thank you

A *.mdl comes from StarCD and not from CCM+. Just use the "save as coded" within ProStar to get the files you want.

Use the EnSight-Format If you want to postprocess StarCD cases with paraview. It might work.

Thank you very much Joern,
best regards

Hello,
I would like to know how StarCCM+ works, what file it creates, etc...
Can I only translate mesh from StarCD in OF or is there also a way to translate mesh from StarCCM+ in OF?

Thanks for any reply

Thank you Joern!
Ok, I know "ccm26ToFoam".
And for the converse way? How can I export a mesh from OF to StarCCM+?

Thanks

CCM+ can read fluent data. So use for instance "foamToFluent". Other ways are also possible.
