pp compile issues

Post by ywan459 »

Hi there,

I have a compiling issues with the syrthes-pp modulus. Error stops whole compilation and did not produce syrthes-pp modulus. And I cannot run multi-process calculation (basically it showed the message of "cannot find syrthes-pp").

Please refer to the attached log files from the installation. It seems something wrong with scotch. My system is
1. Windows Subsystem Ubuntu 20.04 LTS on Windows 10.
2. Package: Debian OpenMPI Open MPI: 4.0.3

I have successfully compiled code_saturne 7.0 on this OS, and get lots of decent CFD results. Both code_saturne and syrthes GUIs works very fine as well. I am currently working coupling of syrthes and code_saturne for the better heat transferring analysis. This error really stops me.

I am not sure whether it is missing a lib or setup issue. Thanks for any helps in advance!.

Regards

OK, I worked it out by myself. Not a perfect solution, but at least the solution enables me to run problem solution on Syrthes 5.0 with multi-processes.

I found the issue occurred when compiling with SCOTCH. I modified the makefile under syrthes-pp folder. Basically following the README instruction as below, and re-compile everything again.
### Some trouble with METIS or SCOTCH install ?

If you have any problem with METIS or SCOTCH install :
> - For serial calculations, you don't need METIS or SCOTCH : don't install them ! (see setup.ini file)
>
> - For parall calculations you need METIS _OR_ SCOTCH
> * in case of problems with METIS install, don't install it, edit the file
> **syrthesx.y/src/syrthes-pp/src/Makefile** and remove the following

> * in case of problems with SCOTCH install, don't install it, edit the

When running the job, remember to change "Domain partitioning" in "Running options" tab to METIS. All done.

However, I do not know whether this solution would affect the coupling with code_saturne. My coupling case fails to run and I am still trying to debug the issue now.

Edit:

Ok I partially worked it out. This should not affect the coupling as both METIS and SCOTCH is only for partitioning mesh. Just make sure that we both choose METIS for code_saturne and syrthes in the running options.
