With updating from Star-CD V3.24 to V3.26/V4.0, I also updated my OpenSuse installation from V9.1 to V10.3.

The old setup (OpenSuse 9.1; Star-CD 3.24) worked fine with Intel Fortran 8.1, the new Installation doesn't. Neither with Intel Fortran 8.1 nor with 10.1. Star-Support tells me, I will definitely need Intel Fortran 7, which Intel stopped supporting quite some time ago, and my usual software dealers are not able to deliver any longer. In any case it would be annoying to buy outdated software. Is there anyone with similiar problems and maybe a solution to them?

- Is it really the Intel compiler version that causes the trouble, or could it be because of changes to the GNU-Libraries in OpenSuse 10.3? If so, can that be solved by installing older GNU-versions?

- Any hints on soruces for "antique" Intel Fortran Compilers?

Thanks for any helpful comment, Christoph

I think compiler version does not effect anyhow your code. I am using Star-CD 3.26 with Absoft Fortran 7.5(old version) on OpenSuse 10.3. Before, I had the same version of Star-CD and fortran with OpenSuse 10.2, and even with Suse Linux Enterprise Desktop 10. My friend uses Open Suse 10.3 with Absoft Fortran 9. So, try Absoft fortran.

What does not work with your new setup? What are the errors that occur?

AFAIK compilers only influence STAR when using user subroutines, do you user it?

Yes, sorry, Star does run generally, but can't handle user subs. An example of what I get in return to "star -ufile" is listed below, along with the error message when trying to run a model with user subs.

Response on "star -ufile"

# star -ufile

PNP: Analyzing User coding in "ufile" directory. PNP: compiling /opt/intel/intel_fc_80/bin/ifc -w -KPIC -WB -c bcdefw.f -o linux_2.4-ifc_7.0-glibc_2.2.2-dso/bcdefw.o PNP: ifc: warning: The Intel Fortran driver is now named ifort. You can suppress this message with '-quiet' PNP: Building New dynamic shared object "ufile/linux_2.4-ifc_7.0-glibc_2.2.2-dso/libstarusr.so" PNP: packing ufile/linux_2.4-ifc_7.0-glibc_2.2.2-dso/bcdefw.o PNP: packing ufile/linux_2.4-ifc_7.0-glibc_2.2.2-dso/libstarusr.a

Error message after starting the model:

Sounds like a problem of library definition. AFAIK STAR is compiled using the absoft compilers and this is also the prefered one for usubs. Ask support for best version of Absoft compiler to fit to 3.26. BTW your 3.26.000 is very old. In my eyes there is no need to stay on this version of 3.26 anymore....

According to the installation guide, there are two compilations of Star for Linux_x86 available. One compiled with Absoft 8.2a (patched once), and another one compiled with Intel ifc 7.0. I installed the latter one.

But thanks for the hint on 3.26.000. I might try an update there first, before searching for Fortran compilers.

Hi Christoph,

I am wondering if you did the call of star -ufile and the star-run itself on the same machine or on different once? Did you use -noufile for the solver call?

And you could also try this:

http://www.cfd-online.com/Forum/starcd.cgi?read=12947

Yes, it was the same machine, directory and model files. The model itself had been created and run smoothly under my old installation (OpenSuse 9.1, Star 3.24, Intel Fortran 8.1). But no, I didn't use the -nofile option.

Wow, thanks so much - that link does look promising! Unfortunately, I won't find the time to try it today, and will be away for the next 2 weeks, starting tomorrow. I will let you know then, what came out of it.

Again, thanks a lot, Christoph

Dear usker,

I am ready to give up on trying the various Intel compilers I have at hand.

You said you are running Star-CD 3.26 with Absoft 7.5 under OpenSuse 10.3. Have you tried using user-subroutines with that setup?

Thanks for your reply.

I use version 7.0 of the compiler with Suse 10.2 for the 32bit version of star 3.26 and it works very good.

For star4 you can use the portland compiler PGF6.2. To get the compiler installed you have to tweak the file "makelocalrc". The compiler runs for 2 weeks after installation in demo mode.

Yes, I run it with user subroutine, it has been working well by now.

Regards
