open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello JMH,

As suggested I switched off the hydrodynamics and only using the tracer solver and now the solution has improved considerably, very close but still no cigar :). I am still running another case and will be happy to share the results shortly.

Hi Sébastien,

Sure I can send all the files, I wonder if I can upload .slf and .cli file here. I am am plotting the analytical solution using excel and transferring the numerical solution from tecplot to excel.

I have one more question if I want to attach a settling velocity to the tracer , which is the subroutine that I can make changes to ?

All help is greatly appreciated.

Best regards,
Sumit

Hello,

You can zip all file and should be able to upload the zip.
Otherwise, you can send the zip directly to This email address is being protected from spambots. You need JavaScript enabled to view it.

(VITCHU is the subroutine)

Thanks.
Sébastien

Hello Sébastien and JMH,

I am attaching a zip file here containing all the files that I am having for ADR solution. After the last post, I have tried reducing the time step and refining the mesh further, although the solution has improved, but it is still not capturing the numerical solution.

Once again I have switched of the hydrodynamics, made the bed friction zero and imposed a constant u velocity of 0.03 m/s in a channel of about 10 KM length. The analytical and numerical solution are compared at x = 2.0 KM from the upstream end in the middle of the channel and at 5 m from the bed. The channel is 10 m deep.

In the attached zipped file you will also find sumit.f having routines where I am making the required changes. If you could kindly take a quick look and if you have any further suggestions I would really appreciate.

With kind reagrds,
Sumit
