Dear Developers,

Since the OpenFOAM core dumping all the time on my IRIX system, (execpt icoFoam and a few solvers), so I am wondering do you have a plan to release a testsuite just as what gcc did to fully test the final installation and all the FOAM_Template_Library? I noticed there are some in application/test dir, but I think it is far from enough, isn't it?

Looking forward for your reply! thanks.

Daniel

Daniel,

I'm not a developer, but I think that the cases in the tutorials section might be adapted for use as test cases, with the addition of what should be some relatively simple code to compare the results of running them, or simplified cases of them, to results generated by the developers and thought to be 'correct'.

One problem is that some of the cases that are run by the main Allrun script in the tutorials directory actually take a very long time to execute on a uniprocessor, so to just get a sanity check you'd need to pare down those cases quite a bit.

Also, there would be a lot of data involved unless some steps are taken to log it less frequently and/or compute using coarser grids. I think that seeing whether a particular solver is working as the developer expected on a simplified tutorial case would be a useful step in the right direction.

Regards, Graeme.

Thank you, Graeme!

There's a strange problem on my IRIX machine.
I installed gcc-4.3.0,
binutils-2.18.

After a very difficult compilation, what's strange is I can build icoFoam and it runs without core dumping, but turbFoam or oodles core dumped!
Interestingly, those that need link the libraries
-incompressibletransportModels
-incompressibleturbulenceModels
are all core dumped!

The reason I posted my first post is that I just want to have an easy way to test files like these two:
-incompressibletransportModels.so
-incompressibleturbulenceModels.so

And also, I turn to guess that it is my gnu-ld is "somewhat" or "a litte bit" incompatible with my system.

So finally I implement all my transportModels and turbulenceModels which are needed by turbFoam and the like to finiteVolume and rebuild the new finiteVolume.so.

Now turbFoam -> PASS!

Daniel

To test using the tutorials there is the Alltest script in $FOAM_TUTORIALS which will just run a few iterations.

Hello, all,

There seems to be one step left for me to make it work on IRIX, it's all about MPI.
Here's the error message.
I dont understand what does this line mean.
libexc(513638): ERROR __exc_get_fde_name: Couldn't find any name at 0x60204334

Any help much appreciated!
Well, I can run icoFoam very well without using mpirun.

Daniel

Good for you! :-)

I've given some thought to implementing the ideas I floated in my previous message; I'm not likely to have time to do much with this in the next couple of weeks, but perhaps a month from now...

I saw Mattijs' mention of the Alltest script. I haven't looked at it in detail and I wasn't clear about what it did, but it still seems to me that if we have a transient solver it will still be worthwhile to have a set of tests that can run to completion and give a fully developed flow in a reasonable amount of elapsed time (albeit on a coarser mesh), and generate sort-of reasonable data rather than just doing a few iterations as Mattijs says the Alltest script does.

I'll plan on making that happen, but not tomorrow.


Regards, Graeme.

Thank you, Mattijs.

Yes, I agree, I have examined the Alltest file this afternoon, and that's not what I want.

a coarser mesh plus certain solver is a good choice.

Yet what if a solver or a utility cannot run at all, and core dumps all the more? How can I diagnose the problem? For me, the hard time arises when debugger (dbx or gdb) and "par -s -SS" and the like couldn't give me enough useful information.

Thank you all the time, Graeme.

Kindly Regards,
Daniel
