Re: Atmospheric fow model/SIGSEGV signal (forbidden memory area access) intercepted!
I am definitly not an expert of Code Saturne, neither in linux authorization. Firstly, reading the setup.log, it seems that you did not defined all your boundaries : Boundary: top type: undefined zone id: 4 Boundary: wall_e type: undefined zone id: 5 Boundary: wall_w type: undefined zone id: 6 Then ...

Humidity Boundary condition Atmospheric module
Dear all, While using the humid atmospheric module, I noticed that if the meteo file wasn't provided, it is not possible to define humidity for inlet or inletOutlet : I tried several things, including neumann, diriclet conditions, but not a single one worked. Is it mandatory to provide meteo file if...

Re: z_ground divergence atmo module
Thank you very much, I had come to the same conclusion, z ground could be the problem but I had not debugged. Please, let me know then what could be the solution,
Best regards,

Re: z_ground divergence atmo module
I am facing a new initialization problem with the atmospheric module: For two days my simulations have failed, with a nan error on initialization: Invalid (not-a-number) values detected for a field. The errors seem to come from this step of the initialisation of the atmosphere : L2 norm of F_ext=nan...

Re: Solar Load
Thank you very much ! Any form of help is welcome.
Yes indeed, I think I saw this difference, if i rember well, the former is computed rayso.f90 while the second one is computed in rayir.f90.
Is the direct radiation automatically directed downward ?

Re: Solar Load
Hello Yvan,
Thank you for your support,
Unfortunately I don't have any errors, I'm just looking for advice / documentations / template cases / help. Anyway, just something to lead me to proper use of solar load but I'm stuck right now....

Re: Solar Load
I am still wondering how to impose Solar Load with zenith angle, does anybody know how to do it ?
Otherwise I will be interested in the setup files,
Many thanks by advance,

Re: z_ground divergence atmo module
Thank you very much for shedding some light on the third point. Indeed I was quiet confuse on an other case while using a drift scalar because i had an error with z_ground related to drift_tau. In order to fix it, I changed z_ground in c_use_physical_properties this way : if (!strcmp(f->name, "...

Re: z_ground divergence atmo module
I had no user files for this case, and as far as I remember, this issue has occured on cases with no user functions. Here is the RESU file compressed. By the way, how exactly does the wind profiles is generated ? If i have a building roof on my boundary, z_ground is 0 on it so the wind profile won't...

z_ground divergence atmo module
Hi all, I have used the atmospheric module for a few cases, and I have randomly some errors linked with the divergence of z_ground during the first time step. It happens when I want an automatic idealized wind profile, but not on all meshes. I found once that my ground was higher than 0 in the z dir...
