Hello Yvan,
Yes it runs in serial mode. Unfortunately the calculation crashes in case of n > 2 processors without error log. Moreover the listing file does not seem to contain some information about the error.
Thank you for your attention.
Kind regards,

Re: Running parallel calculation from Terminal
Hello Mohammad, Thank you for your reply. However I get the same error with your command: -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 1. NOTE: invoking MPI_ABORT causes Open MPI to kill all M...

Running parallel calculation from Terminal
Hello, I have tried to run a case (with internal coupling) in parallel mode using the version 5.0.10 of Code_Saturne by means of the command code_saturne --nprocs n . However it crashes and I do not really see the reason why. Does the parallel mode depend on the number of meshes for example ? Thank ...

Merkle's model (cavitation module) in Code_Saturne v5.0
Hello, I have noticed that the source terms from the Merkle's model seem to be computed differently in the sources of the code. The Theory Guide v5.0.0 (page 145) indeed indicates the factor alpha * (1- alpha) instead of alpha for m- or 1- alpha for m+ according to the original model [1]. Moreover a...

Restarting a calculation without the GUI
Hello,
In a few words, what is the more convenient way to restart a calculation without the GUI please ?
Thank your for your comprehension.
Best regards,

Set listing verbosity options
Hello, I would like to manage the verbosity within the listing file either in order to discard the writing of boundary mass flow information or by setting a writing time step. This could be very helpful in order to lighten the listing file size (I am indeed dealing with FSI calculation through inter...

Re: FSI internal coupling and sub-iterations
Hello, Thank you for the reply. In the file strdep.f90 and in the case of nalimx > 1, then the newmark algorithm is recalled until reaching convergence through the threshold epalim ? Moreover, only the first components of the arguments of the newmrk subroutine which is called in the program seem to ...

FSI internal coupling and sub-iterations
Hello, I am dealing with FSI internal coupling calculation within Code_Saturne and I would like to know how to change the force relaxation term used in the sub-iterations which maximum number is driven by the variable NALIMX ? According to the documentation, the variable CFOPRE is supposed to do so ...

Re: Newmark-HHT algorithm in Code_Saturne
Hello, I think I get the issue relating to the mass structure: I indeed simulate a 2D-like simulation (height of 1e-6m) and I entered before the linear mass instead of the real mass within the height 1e-6m. Nevertheless the structure mass is now very low and leads to calculation instability despite ...

Re: Newmark-HHT algorithm in Code_Saturne
Hello, Thank you for these details. I am actually dealing with the simulation of structures in a fluid. I should observe the added mass effect through a reduced frequency of structures displacement but the result does not exhibit any effect (the structure oscillates with its natural frequency). I ha...
