Patches for OpenFOAM 1.7 on MacOS X
 

Hi!

Attached there are two patches that patch the OpenFOAM and the ThirdParty-directory of the new 1.7-release.

For installation and requirements (case sensitive file system) see for instance http://openfoamwiki.net/index.php/Ho...enFOAM_v16_Mac (if somebody feels like rewriting/adapting that: go ahead)

Some remarks on the patch:
- only the darwinIntel64-architecture has been tested
- the patch assumes that you use gcc 4.5 from MacPorts. If you don't: replace all instances of the form gcc-mp-4.5 with the compiler of your choice
- tecplotWriter does not compile
- as soon as paraview is compiled the PV3FoamReader will compile. It will load as a plugin into paraview. Nevertheless: it will crash paraview as it needs a different version of the libstdc++.6.dylib than the one paraview uses (paraview fails to compile with the same compiler as OF). Only solution: remove the libPV3FoamReader_SM.dylib and use the OF-Reader built into paraview. Alternative would be to compile OF with the v4.2-compiler that comes with MacOS X

You rock!

Thanks

Actually it was quite easy as I had maintained patches of 1.6.x anyway and there were only two changes required

Bernhard

Have you guys tried this?

http://www.parallels.com/uk/products/desktop/

I recently switched to this instead of dealing with the mac-issues.

Since I dont do any serious work on my mac, but only write code and run simple tests I find this
to be an incredible piece of software.

You can download a free trial version for 2 weeks.

Cool / I'm currently compiling with gcc-4.3, so far so good !


Yes, I know this software / I use VMware when Windows is needed ... It's good to have a native version of OpenFOAM on the mac, easier to prepare cases before sending to the cluster.

Thanks !

Working with finkproject compilers
 

Hi,
Just thought I would let everyone know that the patches work as advertised with fink project compilers (gcc45 package).

To do modify the patch file (OpenFOAM-1.7-Mac.patch):
Replace -mp- with -fsf-
Replace 4.3 with 4.5


Chris Butler

Bernhard,
thanks a lot.
Wonderful! The OF1.7 mac port is now ok to run on snow leopard 10.6.3 with gcc4.5 installed by macports.
Because of the error of 'time', the foamToTecplot360 has not been compiled.
The Paraview 3.8 for Mac is now availabe for post-processing. :)

Problems OpenFOAM 1.7 mac
 

Hi all,

I have run into some problems with OpenFOAM-1.7 on mac os 10.6.4. The tutorial for nonNewtonianIcoFoam appears to fail (due to a solution singularity).

This at first glance appears to be due to blockMesh failing to produce an adequate mesh (see the attached file). The tutorial correctly executed with the debian 1.7 install (and 1.6 source install on CentOS).

Has anyone else had any problems? I have created meshes which do not contain the arc object without any trouble.

Any feedback would be much appreciated.

Cheers,
Chris Butler

P.S. If this post is in the wrong forum my apologies.

I can reproduce that. Which compiler are you using (I use gcc-4.5. My 1.6/gcc45-installation is broken, so I can't check. I'm suspecting the compiler because it is my impression that he handles FP-operations somewhat differently). If I do blockMesh with 1.6/gcc45 then checkMesh and the solver have no problem, so the problem seems to be located with blockMesh

Bernhard

The weirdness continues: if I do the blockMesh with with 1.7/gcc45-debug(!) I have no problem. So it seems that something is going wrong during optimization (in gcc45)

BTW: have a look at the mesh in paraview. No wonder checkMesh doesn't like it.

I just tested (I have compiled OF-1.7.x with gcc-4.3.4) / no problem here with this tutorial.

Update: I repaired my 1.6/gcc-4.5 installation. Now the following happens:

1.6/gcc-4.5-Opt: broken Mesh
1.6/gcc-4.5-Debug: mesh OK
1.6/gcc-4.3-Opt: mesh OK
1.7/gcc-4.5-Opt: mesh broken

So the problem seems to be gcc-4.5 with optimization. The remaining question: does this only happen on a Mac or elsewhere, too?

gcc 4.4
 

Hi,
I am building OF-1.7 with gcc-4.4 on both OSX and linux, however, I do not have a linux box with gcc above 4.4.4. So if anyone could test this tutorial on linux with gcc-4.5 it would be appreciated.


CB

blockMesh (OF-1.7) runs correctly on the (nonNewtonianIcoFoam) tutorial under both OSX and Linux when using gcc-4.4

would you reproduce it?

Leo

I get a similar error for gcc 4.4.4 for both linux and mac OS (OF-1.7). Unfortunately I don't know enough about the code (or the chemistry) to help you much further, however, it seems like there may be some stability problems with the equations you are solving. I noticed 2-3 time-steps before the temperature dramatically increased tmax = O(2500K). I am completely unfamiliar with the problem at hand, however, this did not seem consistent with the previous time-steps.

Cb

On my linux-workstation (gcc 4.4.0) I get the same error (with a slightly different time and a different temperature. Funny thing is that when I run it in Debug-mode (same sources, same machine, same compiler) it is slightly different again

So it is not a Mac-problem but a problem with the case (and possibly the compiler)

Bernhard

Bernhard,
I just check the log file for the calculation on Linux port again, you are right. it's same error as you said that with a slightly different time and a different temperature.

It should be reported to developer as a bug.

regards,
Leo

You're right. Go ahead: report

Sorry. Just noticed: you already did
