Re: problem using lagrangian module with code saturne 2.0.2

Probably a mistake in error message.

Replace "OR" by "ARE" and the error message should be clear.

By the way, this topic should not be in installation issue but in Code_Saturne usage.

Re: Can the 'ncaptm' be modified?

Hello,

No, you must modify ncaptm in source code and reinstall Code_Saturne.

Re: Numeric instability switching from 2.0.1 to 3.3

Hello,

Did you compare 2.0 and 3.0 listings?
Could you try with IDTVAR = 0 (unsteady algorithm, with constant time step) and also with another turbulence model (eg: k-eps)?

Re: Problem results

Hello,

Why you did not use a symmetry condition on the upper wall ?

Re: How to link separate mesh parts?

Hello,

This is probably a merging problem. You can open the JOINING.case to see the "joined faces".

You should look into all the listings to get the error.

Re: Calcul erreur juste après la fin des itérations

This warning appears only when iwarni(ivar) > 0 (verbosity lvl). It indicates that the iterative process on RHS does not converge. This warning is not very important for steady calculations and should disappear when the flow is converged.

you can refer to the theory doc. for more details.

Hello,

Yes (grep cmd help me)

iscalt, itotwt and intdrp are the pointer in rtp to "LiqPotTemp", "TotWater" and "NbDrop" variables.

Re: Impose 2 nd order scheme for K-epsilone

Hello,

What error ? You cannot use order 2 in time for k-eps in Code_Saturne 3.0 (I think the error message was clear).

Re: Output of Yplus values on the main volume mesh.

Hello,

1) no
2) no

You must use distpr and distyp subroutines to compute y+ in the fluid domain. Set ineedy = 1 to get y(iel) and use distyp to get y+.
