Hello, every one!

I hope this message finds you well. I've been using Telapy to interface with Telemac2d v8p4, which has been quite smooth. However, recently, I encountered an issue when switching to a new case study. The primary differences between the new and original cases are the increased number of point sources and the consideration of spatially distributed bottom friction coefficients and infiltration parameters. Unfortunately, I encountered the following error message before the computations began, making it challenging to identify the cause. I would appreciate any suggestions or insights that could help me address this issue.

To further elaborate, in order to identify the issue, I ran the case using the Windows version of Telemac v8p4. I encountered the error 'Program received signal SIGSEGV: Segmentation fault - invalid memory reference.' Based on previous forum threads, it might be an issue with my subroutines. Therefore, I've attached the 'user_fortran' file, and I would greatly appreciate it if someone could assist in pinpointing the problem. (Given that 'user_nomvar_telemac2d.f' and 'bilan.f' were successfully used in previous cases, the problem is likely to reside within 'runoff_horton.f').

After conducting tests, it appears that the same issue persists even when disregarding the 'user fortran' options. It seems that the problem doesn't originate from the subroutines. However, I'm genuinely unable to pinpoint the problem and sincerely hope someone could offer some guidance.

Hello,

As told a few tims, if a segmentation fault or a NaN (Not a Number) occurs, you should use a debug configuration with debug options to investigate.
See e.g. the S11.gfortran.debug configuration in the $HOMETEL/configs/systel.edf.cfg configuration file, in particular the flag fflags_debug_gfo for gfortran compiler.
fflags_debug_gfo: -g -Wall -fcheck=all -fbacktrace -fbounds-check -finit-integer=-1 -finit-real=nan -ffpe-trap=invalid,zero,overflow

It will show in which subroutine the issue/nan/segfault occurs, the first suspicious line and may help you to change something in your computation.

Hope this helps,

Chi-Tuan

Thank you for your reply!

I previously tested it on the Windows auto-installed version. Now, I've checked my cfg file on the Linux version (attached). It seems to include debug settings. However, the additional error messages haven't provided me with insights into the root cause of the issue. I'm not sure if I might have misunderstood something.

Regards,
WSY

The issue has been resolved. Due to an excessive number of source points on my end, it was necessary to further increase the value of NMAX in declarations_special.F (the previous setting of 3000 led to errors). If anyone else encounters a similar issue, feel free to refer to this solution.
