Hello, I still don"t understand why sometime the logging is correct and sometimes not. (both in v4.2.1 and v4.3.0. I am interested in postprocessing the fan cells selection. For now I am stuck with 4.2.1 (v4.3.0 gives me full of NaN during computation for same settings). My guess is that i have...

oh wrong info, this is not related to 4.2.1/4.3.0 because i also have wrong logging info in 4.3.0.
this must be caused by the code i've changed; but this is very curious since i didn't modified any of the lines dealing with fan cell flag or volume computation.

Hello, Just an idea : have you checked if you have several blocks in your model ? If yes, try extract block filter and select the block where there is velocity. A good hint is the field name in the combobox if it is written something like "(partial)" after the name, then it may means that ...

Hello, I need the LD_PRELOAD in the runcase script otherwise the computation fails (with a python error message of the kind : could not import site). I tried to dig a little further in this problem and noticed that it may not be related to CS but to paraview. Indeed I have 2 installations of paravie...

Hello, Yes this is working pretty well. Thanks for the fix. I also notice a strange behaviour between 4.2.1 and 4.3.0 : In 4.2.1, my fan model does not log any volume for my fan (adding extra code to report cell count show 0 cell in the fan). But computation results show that the fan is properly wor...

For information, I reconfigure my case for version 4.2.1 and simulation is running.
This seems to be a problem with version 4.3.0.

Has anybody observed the same behaviour ? or do i have a corrupted installation ?

Hello, In CS 4.3.0, i am trying to set up a case with a fan. I have only added the cs_user_parameter-fan.c file in SRC and then run the case. The computation fails with the following message : cs_field.c:2127: Fatal error. Field "fans_ids" is not defined. Call stack: 1: 0x7fc782f23103 <cs_...

Hello, Thanks for replying, cfg file is as : [install] ### Select the batch system type and job template. batch = SLURM ### ... ### Optional path to sourcable shell environment initialization file ### (similar to .profile or .bashrc, specific to Code_Saturne). rcfile = /home/applis/code_saturne/4.3....

Hello, Thanks to a previous post in the forum, i managed to enable coprocessing for cs v4.3.0 (very very nice feature !!). Like mentionned in the post, i have to set the LD_PRELOAD variable in addition to the python / paraview variables. Such that my lunch script has the following decalartions in pr...

Hello, A small bug (or feature ??) for slurm batch configuration (CS V4.3.0). CS throw an error when trying to use a slurm partition that is time unlimited : File "/home/applis/code_saturne/4.3.0/lib/python2.7/site-packages/code_saturne/cs_batch.py", line 65, in parse_wall_time_slurm t = t...
