Hello, Version 2.0 can also support MED 3.0, but you have to build it with a MED 3.0.x library, not with a MED 2.3 library. Starting with 2.0.2, the automatic installer should install MED 3.0 instead of MED 2.3, but if this fails and you already have a MED 2.3.6 installed in system paths (such as wi...

Hello, I just tested this, and there seems to be a bug in the handling of alternative compute versions. The bug only occurs if you use an absolute path, so since you seem to have a consistent naming scheme (which is recommended), you should be able to ignore the bug using: compute_versions =noeuds i...

Hello, I do not have time today to check all details relative to your first question, but I can add the following: The energy equation should be that of the theory guide, but when in doubt, the comments and examples at the beginning of the user subroutine should help (if in conflict with the theory ...

Hello, With version 2.0.x, the boundary conditions for gas combustion are set in usd3pc.f90, not usclim.f90 (things will be more consistent starting with 2.2). Also, As another thread on this forum already shows (for version 2.1), I do not believe the gas combustion module works with the GUI, so you...

Hello, Natural convection can be quite tricky to model, so difficulties in convergence might not be due to an error in the source term (which I'll let you and others cross-check), but to other causes. Are you running a steady or a transient calculation ? (try transient if steady does not work) Is yo...

Hello,
How far did you get (edited usppmo.f90, compiled it, ... ?)
Best regards,
Yvan

Hello, The .syr file format has changed between Syrthes versions 3.4 and 4.0, so the error you obtain is not surprising. Code_Saturne 2.2 (compatible with Syrthes 4) should be released before the end of this month, so I recommend to wait a few more days (if you have the GNU autotools, flex, bison, p...

Hello, Either inlet with velocity = 0 or a wall should be OK. Did you define the gravity direction ? Also, I am not sure natural convection works well with the "steady" flow option, so if this is what you are using, you may want to try to switch to converging an unsteady calculation. Best ...

I just tried running with bounds-checking enabled, and do not reproduce your error, so the issue I had in the previous post is probably only a minor bug. I am not running with version 2.1.4, but the 2.1 branch head, which you could obtain using: svn checkout http://code-saturne.org/svn/saturne/branc...

Hello, Using a the code compiled in debug mode (with bounds checking enabled), I get an earlier error: At line 105 of file /home/yvan/Code_Saturne/saturne-2.1/src/cogz/ebuver.f90 Fortran runtime error: Index '0' of dimension 1 of array 'visls0' below lower bound of 1. Looking at the source code, it ...
