code_saturne User's Forum

Hi Yvan

I wiped clean my system and installed latest CAELinux2013 which has code saturne v3.1. I still cannot update to code saturne v4 without immense issues. Anyway, its a clean install.

I am running old case with a user subroutine called extra operations to calculate lift and drag coefficients. In previous version, it used to work just fine generating coefficients.dat file.

In this version, it does not create coefficients.dat file but does compile it without errors. I mean compilation is fine (compile.log) but doesn't write any file. I have compared old and new files in reference directory. I did not spot any difference.

Kindly guide. Related files are attached. Thanks

Hello,

I do not see any obvious issues in your subroutine, so I do not know why it does not work.

Your XML file seems to indicate you are postprocessing the "efforts" (actually stresses) at the boundary. Do make sure this is the case, to ensure "ineedf = 1".

In any case, 3.0.0 is an obsolete version: the current 3.0 release is 3.0.8, and contains many bug fixes, which might be related or not.

Do you need version 3.0 ? Recent versions of Debian or Ubuntu have versions of 4.0 or 4.2 packaged, which do not require a complex install. CAELinux was very dynamic a few years ago but seems making quite slow progress as a distribution nowadays.

Regards,

Yvan
