hi,
 
Where can i get detailed info about the Numerical methods used in CS .. for example  FLUENT documentation .... there are 3 solvers ... namely, pressure-based implicit, density-based implicit and density-based explicit. A detailed theory about these solvers is given in FLUENT..... so  is there any documentation for CS available in ENGLISH.  I really need these info .. :(
 

Hi,

in Code_Saturne, there are two solvers for incompressible flows and compressible flows. The incompressible solver is the same technology as the pressure-based implicit algorithm of Fluent. For the compressible flow I do not know.

The theory manual is partially translated but covers the two solvers.

All helps for translation efforts for sources or documentations are welcome

thnxxxxxxxx ... how i wish i knew French instead of German :P
 
could u please tell me why i am having this error even though i can run other cases on the same computer but this case (different mesh) is showing this error
 
Please find  listing file and xml file

Hum, it seems that the result of the mesh preprocessing is not found by the solver.
  Reading pre-preprocessing:  preprocessor_output

/home/tksen/Code_Saturne/src/bft-1.0.8/src/bft_file.c:771: Fatal error.

Error opening file "preprocessor_output/n00001":

  No such file or directory

Could you check in the file listenv.pre if the mesh file is found by the preprocessor Enveloppe?

Thnxxxxxxxxxx ..... i solved the problem  somehow :D

Hello Mubashir,
You can find more information about (part of) the theory behind the scene of Code_Saturne in a paper of 2004 available here:
http://www.latp.univ-mrs.fr/IJFV/IMG/pdf/saturne.pdf
This is far from complete, but it will give you an insight on the theory. Let us know if you need more details on specific points.

At first sight it seems to quite informative ..... let me go thru it and find if it has the info which i need
