open TELEMAC-MASCARET The mathematically superior suite of solvers

When I run the model, I get the situation like this and it cannot run. Could anyone told me how to deal this problem?

Exception in thread Thread-2 (print_twice):

Hi
There is somewhere in one of your file a character which is non utf-8 compliant...
This could be a comment or something else...

Yes, I think this information occur when the program read the list and print it on screen. But I do not know the exact cause of the problem. Could you give me more information? I attached the screenshot. Hope your rely.

Hard to say as the screenshot doesn't give more informations on crash.
As there is a mention of an ascii file this is potentially the cause of the problem.

Do you mean the problem may be cause by an ascii input file of the case?

By a wrong character in an ascii input file yes

Hi,
I found even the python threw that error, the fortran program still run well. I attach the temporary file. Does it affect the final result of the run?
By the way, could you tell me how to set a tracer as an active tracer such as salinity or temperature making it have effect on the density of the water?

.log are not permitted (see rules)
Final result should not be affected by running fortran program as this is just a python problem.
Not sure to fully understand your question.
For me, only Temperature and salinity could have an effect on density in telemac 3D by default. Defining a new active tracer implies modifying some subroutine and adding new density laws...

For the first question, I did not get the final result file after the calculation. But the log files show the fortran program finished correctly. I think the problem should not from the coding of the input file. Maybe it comes from the python itself. If I comment the python sentence that throw the error, the screen print disappear but the fortran program works well. The error occurs in /python3/execution/process.py, in line 696:print(dat.decode('utf-8')).
For the second question, how I can enable the calculation of temperature and salinity? Just add tracers named temperature or salinity? I did found the detail description users' manual. I

Hello,

You should read the TELEMAC-3D user manual and the TELEMAC-3D examples more carefully:
- define a tracer with name TEMPERATURE or SALINITY,
- choose how you want the density vary with the keyword DENSITY LAW.

Hope this helps,
