open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone!
I have recently encountered some difficulties. I found an error while running my program and this error still cannot be solved after many debugging searches. I want to define the flow field by reading the flow rate file in the path through the fortran subroutine. In my previous debugging, this file was successfully read and output, but there was an error when I applied it to telemac calculation. Forgive me for not being a native English speaker, many expressions may not be clear enough. Now I am uploading my documents, including fortran files, and hope that someone can give me some advice, thank you very much!

This attachment contains the missing fortran file and my flow rate file from the previous post.

Hi all!
I seem to have found the cause of the problem, because my fortran subroutine was written incorrectly, now I have modified the program, I am sorry to take up the forum space.

Hello Xinjie,

Perhaps you can write what was the cause of the problem as it may help other users (I have not opened your files as you solved your issue).

Sure, I'm happy to share my experience!
The main cause of the problem was that I failed to assign a variable to the loop in the fortran subroutine, so that it did not read my file correctly. Below is my corrected subroutine file.
