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 you ...

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 ...

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 ...

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.

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 ...

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 :
