open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I was trying to modify the subroutine STRCHE in order to give Chezy Coeff. to each point. The idea is to assign a time and space-varying Chezy Coeff. to each node. But I failed to do this because the STRCHE seems to be invoked just at the beginning. So the Chezy Coeff. will not change over time. Besides I noticed that the water depth variable H%R seemed not initialized because the value I got was 1.798E+308.



How could I give a time and space-varying Chezy Coeff. to each node? Thanks!

Hello,

Yes, you are right, the subroutine STRCHE is called only once. To specify time and space varying friction you must take subroutine CORSTR in your FORTRAN FILE, this one is called at every time step.

With best regards,

I've modified subroutine CORSTR. Now it works well.
Thank you!
