Hello,

For this kind of issue, I have 2 suggestions:
- read carefully the TelApy user manual, in particular subsection 4.1.2 "How to add access to a new variable". I am not a specialist of this module, but I can read that using a script does the job easily (but you have to know what you want to declare as a new variable, the script cannot guess for you). I have just tried and it generates the enclosed file e.g. (if DSCE is supposed to be an 1 dimension array of double precision), you also need to change the declarations_telemac2d module by hand,
- or copy and paste of what is done for a similar variable as DSCE, e.g. FLUX_BOUNDARIES.

Anyway, in your implementation, you seem to mix double precision array and BIEF_OBJ or reals (for which %R suffix can be used).

Hope this helps,

Chi-Tuan

Hi
You're right,I have copied and pasted of what is done for a similar variable yesterday.And the compile is successful now.
I can read and change the DSCE in api.
However,when I tried to change the DSCE,the results did not change.
TELEMAC seems to have read the discharge from the cas file in the beginning and stored it for calculation. It means that I changed DSCE but it does not participate in the calculation,the program still used the old value.
