open TELEMAC-MASCARET The mathematically superior suite of solvers

I'm running a parallel 2D simulation on a HPC. It requires prescribing CPU time so that job scheduler can queue up the job accordingly. Unfortunately, there is an upper limit to this CPU time. I have been running a simulation for a week (the limit) but only about 2/3 of the prescribed time step was solved. I'd like to manually merge the T2DRES in the temporary file so that I can use the last computed time step to continue the simulation.

Any help is much appreciated!

Best regards,

Hello,

What you want is gretel_autop. It is compile with TELEMAC. You can find id at %INSTALLDIR%/builds/%CONFIG%/bin/gretel_autop.

Copy it to the folder where you files are and run it.
First give the name of the geometry file (T2DGEO), then the name of the results file (T2DRES) then the number of cores you ran the simulation on.

The merged file will be saved as T2DRES (without 00000-00000 appended).

Phelype,

Thank you very much, thats exactly what I was looking for!

Hello,

Here is the recollection command from the python scripts:I normally use it to merge the results when the computation has finished successfully but the results were not recollected properly for some reason. It is more straightforward than using gretel directly.

Hi Costas,

Thanks for your help again! I like your solution, very simple. Also it's more suitable for merging the files in HPC directory without downloading them to my PC first.

Hi,

There is also a script name gretel.py that will run the merging.
In cas you are in a situation where "runcode --merge" is not possible.

Hi,

I have the same problem but with 3way coupled model. I tried the

But it has not worked.

Could you please explain me how the gretel.py is working so that I can merge all three files?

What was the error with runcode --merge ?

Just run gretel.py -h to see the options.

It always said
"The request is not installed on this system: T2D

I will check gretel

I get an error with gretel as well.

It says:
File /home/USER/telemac/..../python27/gretel.py, line 120, in <module> if not cfgs [args.configNeme].has_key('root'
KeyError: ' '

Not sure what that means.
