New pro-STAR (STAR-CD) to/from
 

New pro-STAR (STAR-CD) to/from OpenFOAM utilities to boost inter-operability
between Star-CD and OpenFOAM. The newer pro-STAR formats can also be used as
a meta-format for converting shape-based meshes to/from OpenFOAM.

Tested with OpenFOAM v1.3

More details are available in
http://www.cfd-online.com/OpenFOAM_D...s/mime_pdf.gif starToFoam-ug.pdf

Quick highlights:

All three-dimensional pro-STAR cell shapes are supported: hexa, tetra,
prism, pyra- mid and N-sided polyhedra. With the recent addition of
polyhedral cells to Star-CD, trimmed cells have become unnecessary.

Arbitrary and integral couples are no longer supported by the converter (nor
by the STAR-CD solver itself).

Baffles elements (i.e., zero-thickness elements inserted into the fluid
domain) are now supported by the converter.

The star4ToFoam converter retains the pro-STAR cell type information.

FOAM/Star (fStar) utilities

fStar-cellTable
Extract STAR-CD cell table information from the pro-STAR input file into a
form suitable for creating a constant/cellTable file.

fStar-cellSets
Use the contents of 0/cellTableId and constant/cellTable to create
constant/polyMesh/sets/... cellSets.

fStar-coordinates
Extract STAR-CD coordinate system information from the input file into a
form suitable for creating a constant/coordinateSystems file for future use
(e.g., with porosities or rotating systems).


foamMeshToStar
Export OpenFOAM mesh into pro-STAR format.
Using the star4ToFoam and foamMeshToStar converters, OpenFOAM support can be
quickly added for many other formats. For example, import/export for I-deas
universal files can be realized with fewer than 100 lines of Perl code for
each direction.

foamMeshToStar works brilliant
 

foamMeshToStar works brilliantly. Thanks for a great tool.

The attached http://www.cfd-online.com/OpenFOAM_D...hment_icon.gif starMeshReader.C.gz file is a drop-in replacement for the existing code. It avoids a typo in the previous code that sometimes caused problems with face sorting. It also partially addresses problems with empty polyhedra faces that may arise from the pro-STAR csimplify command.

sorry about the silly question
 

sorry about the silly question but what have I to do to run star4ToFoam? I put the star4ToFoam in my
OpenFOAM/OpenFOAM-1.3/applications/utilities/mesh/conversion
directory and then run star4ToFoam but the message is

star4ToFoam: command not found

thanx

The API changed a little in v1.4:
For calls with arguments, use the 'writeObject' method instead of the 'write' method (ie, your compile error).

I have yet another version in the works, but still need some time before I can release it.
So you'll have to patch this one youself.

Any news on how your Foam->Star->Foam utilities are coming along?

Here is an update on the aux utility http://www.cfd-online.com/OpenFOAM_D...hment_icon.gif star-inpToFoam - it combines the previous fStar-{cellTable,coordinates} utilities. The fStar-cellSet is considered obsolete.

Hi,

I had a problem with star4ToFoam...

I post the case, in which a very simple mesh has been created with starccm+, then imported in star4, finally exported to allow conversion to foam...

The case may be found at:

Thank u for any suggestion

ccm26ToFoam is still part of the distribution.
Use the following git commands to find it quickly in your OpenFOAM-1.5.x git repository:

git-ls-files --cached | grep ccm26

Matteo, I tested your case
 

Matteo,

I tested your case with OpenFOAM-1.5.x, both before and after applying the lastest bugfix (commit d6b201bb...) and it worked without complaint.

According to your log file, you were using OpenFOAM-1.3 - it might be time to upgrade!

How do I get the results from
 

How do I get the results from OpenFoam back to Star-CD in order to compare and process results in Star-CD?

Hi Kasper, Are you using ST
 

Hi Kasper,

Are you using STAR-CD 3.26 or 4.x?
Have you already contacted OpenCFD about it?
What about exporting both to EnSight format and going from there?

Note that star4ToFoam is now part of the standard OpenFOAM distribution. Thus the previously posted programs are now considered obsolete.

The previously posted fStar-cellTable, fStar-cellSets, fStar-coordinates programs are now superseded by the attached Perl program that combines similar functionality.
