Re: Wall stress discontinuous at restart
Hello, usipsu is a better place than usipes to add ineedf = 1, so you should try this first. If this is not enough (ie. there is no improvement), it would be interesting to see if other fieds (velocity, pressure, turbulence variables) also exhibit a "jump" or not. In theory, a restart shou...

Re: Axail fan modelling usin cs_fan.h
Hello, This seems interesting. Just a note regarding the documentation (or lack thereof). The fan model was implemented and documented in an older code, and the model was recently added to Code_Saturne , but not documented yet. This documentation should be added to the code in the next few months, s...

Re: Face Joining, suspected bug
Hello, You have no joining, I believe because yoour selection criterion is incorrect: "join5 and join 6" means you select faces that belong both to groups "join5" and "join6" (logical "and"). To select faces that belong either to "join5" or "joi...

Re: Axail fan modelling usin cs_fan.h
Hello, The number of iterations might be limited by the fact the solver detects an divergence immediately, so stops there (you have a "nan" right away for the velocity). Did you check the same computation without fan modeling ? I assume the error is due to the fan model, but it is safe to ...

Re: Oil heat transfer with a low flow speed
Hello,
OK, with these type of boundary conditions, thing should work fine (actually, for the outlet, a default Neumann BC should do. The convective part of the thermal flux is not 0).

Re: Axail fan modelling usin cs_fan.h
Hello, The code actually seems to diverge from iteration 1... Could you try running on a single rank (i.e. non-parallel) for an iteration or 2 ? I don't expect this will change anything, but it is a quick check, so I recommend doing it "just in case". Also, do you have access to or can you...

Re: Two-way coupling code_saturne / code_aster
Hello,
I did not find anything obviously wrong, so I am not sure about th cause of th error.
Could you post the whole case (hopefully this first test case is small) so I can try the same case on one of my installs, and see if I have the same issue ?

Re: Restart on windows
Hello,
This is due to a bug which was fixed, but we need to release an updated Windows version (the latest Windows build for 4.1 is 4.1.0, while version 4.1.3 has been released).

Re: Stop to avoid exceeding time allocation.
Hello,
There might be resource limits set on that node.
What does "ulimit -a" (on the login node) report ?
