open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi, I am intent to control the simulation using Fortran APIs when I run a case. For example, I want to stop the simulation at some time step, retrieve some varibales' value and change them.
Recently, I have successfully installed the Telemac (V8p1r1) on CentOS 7 system. I noticed that there's some example code to control the simultion using python script (e.g. TelemacHome/examples/python3/TelApy_api/gouttedo.py) and I run the code correctly.
Although the example python code is helpful to understand the Telapy, I prefer to use the Fortran APIs, based on my programming knowledge, to control the simulation.

Although there's a paper introduced the interoperability applications (both in Fortran and python) of TELEMAC system [1], I am wandering how to access the API_INTERFACE and run simulations when using Fortran code. I also failed to find answers from the develop guide.

Anyone gives some information or example code will be helpful to me. Thanks.

Hi,

There is a user manual for TelApy:
http://ot-svn-public:telemac1*@svn.opentelemac.org/svn/opentelemac/tags/v8p1r2/documentation/telapy/user/telapy_user_v8p1.pdf

I would suggest using the Python version as the Fortran has the following limitations:
- In parallel you need to add the call to partel/gretel yourself
- If you have a user fortran you need to recompile your program with them in it.

You ca have a look at sources/api/homere_api.f for an example of a run using the Fortran API. The easiest way to use them it to edit that file and recompile telemac. then run it using TelemacHome/builds/.../bin/api in the folder containing your case.

Hope it helps,

Hello,

I am currently using TelApy to run a simulation dynamically. In fact, the aim is to evaluate hydrodynamic variables to couple them with a habitat model in python. There are some variables such as velocity gradient, local and convective acceleration, or strain rate, that are no retrived by the command lines stated on the tutorials available . Thus, I calculated both in python and "user fortran". Python script was not efficient to compute hydrodynamic variables that are not retrieved by the FVM or FWM. So I sticked to the "user fortran"

However when I run the simulation via python script, my user functions in "user fortran" folder do not run. I have checked also the user manual, but not found a way to compile my user fortran options.

I cam up with this post since @yugi suggested to use TelApy instead of Fortran API, so we do not need to recompile "user fortran" functions.

I would appreciate any insight on this issue,

Kind regards,

Marcelo
