Error with delwaq coupled with TELEMAC-2D in FVM 9 years 6 months ago #16981

Hi,

I am trying to run a simulation in Telemac-2d coupled with delwaq.
The simulation is run using FVM.
While running the simulation I get the following error with TEL4DEL
TEL4DEL: MAXIMUM MASS ERROR:                  Infinity
          SUM OF ERRORS ON INTERNAL POINTS:                       NaN
Any suggestion to solve the problem, or is it an expected error?
Or is delwaq supported in Telemac when run using FVM?

I have also observed that in FVM result, the model show very less oscillation in the boundaries as compared to FEM, and the results seems to be far superior than with FEM results, if the boundary conditions are provided properly. However with some coupled cases with SISYPHE or DELWAQ I get sometimes failure in the flow model run.
So I wanted to know as whether FVM in Telemac still in intermediate development and testing phase?

I have attached the listing file and steering file.

Thanks,
Gourish

Hello Gourish

Probably you are the first user that chooses these options. Theoretically there is no reason for such an error, however, I'll be interested to investigate a little bit more your case, even though I do not have much time.
So if you can send me your case and I'll check it with Jean Michel.

with my best regards

Dear Riadh,

Thanks for considering the my case for testing.

I have also encountered similar error with sisphye case as mentioned in post
opentelemac.org/index.php/kunena/17-sisy...-suspended-sediments
Which happens to be the same case.

I am attaching the other files.

Thanks and with best regards,
Gourish

Hello Gourish

I tried to run your case, but there are some missing files (mainly those of Delwaq).
Anyway, you can find in attached file a patch that you can add in your sources (and recompile) our in your fortran file.
Please change last line of the call to volfin in telemac2d.f like this (add UDEL and VDEL):

call volfin(...,
& TMAX,DTT,GAMMA,FLUX_OLD,MXPTVS,NEISEG%I,V2DPAR,
& UDEL,VDEL)

also adapt the interface accordingly.

Tell me if it is OK

with my best regards

Riadh

This will fix the same problem of the coupling with Sisyphe.

Hello Riadh,
I tried running the simulation with the changes as suggested by you, however I am getting the following error

I shall check again and try to find out in anything is improper in the modification which I have made in the code.
I also wanted to mention that the missing file of Delwaq indicated in the steering files are the output file from Telemac2d which will be later used to run delwaq simulation. Therfore the simulation can be run without those files.
The sediment steering file is at opentelemac.org/media/kunena/attachments/2535/sedfvmcase.zip. Currently I am trying to run the simulation only with delwaq coupling.

Thanks and with Best Regards,

Hello Riadh,

I am able to now successfully compile and run the simulation with the changes which you have mentioned, I was getting the previous error because I have kept
the volfin subroutine in the steering fortran file instead of changing in the main code.

I am now waiting for the simulation to complete, I shall update you on the status of results on completions of the simulation.

Thanks and with Best Regards,
Gourish
