Hello,
You can run "code_saturne bdump checkpoint/main.csc" to get more info on file and see if it complete (it should end in an "EOF" section).
It has probably been corrupted, but how ? If this occurs at each run, this is an issue. If it occurs once, it is probably not worth bothering to analyze ...

Re: Controlling maximym number of iterations
Hello,
Regarding layer compression, not that code_saturne's algorithm, as called in user-defined functions, works in 2 steps. The first step returns a structure containing an array of vectors, one for each extruded node, and a series of curvilinear coordinates for positioning of each layer. in ...

Re: Question on Steady vs Unsteady RANS in Code_Saturne
Hello,
This really depends on the algorithm you use. In code_saturne, most models assume physical properties do not change too rapidly (otherwise, other types of solvers or algorithms are used, such as the cycle used in neptune_cfd's multi-phase solvers). The segregated nature of the solver in code ...

Re: how can we export boundary pressure results
Hello, there is no direct way of doing this with the GUI.
In user-defined functions, setting a field's 'post_vis' keyword not to 1 but to
CS_POST_ON_LOCATION | CS_POST_BOUNDARY_NR
(or 3) should active the output off boundary values, bit note that those values are not reconstructed, so not exactly ...

Re: Question about the convergence of LES calculations 2
Hello,
As I mentioned in the previous topic, code_saturne can be very sensitive to the mesh quality in LES computations, and there is no simple way to solve this, except to use a more regular (ideally hexa-blocked) mesh, and avoid abrubt changes in refinement.
Some numerical options, such as the ...

Re: Question on Steady vs Unsteady RANS in Code_Saturne
Hello,
Inner iterations (nterup) can be used in the velocity/pressure coupling algorithm mostly for FSI computations, but I do not think they ate required for URANS. The same, sweeps for each solver are used to better handle mesh non orthogonalty (where some reconstruction terms are handled ...

Re: Question on Steady vs Unsteady RANS in Code_Saturne
Hello,
The "steady" option is actually (as mentioned) "pseudo-steady", because it is not based on a steady algorithm, but on an unsteady algorithm with a local time step which allows faster convergence to steady state.
In most cases, the fact that a RANS computation leads to stable or fluctuating ...

Re: Controlling maximym number of iterations
Hello,
We are definitely not planning on building a separate mesher, and plan to continue using external meshers.
The closest we would have to an internal mesher are actually "mesher-avoiding" methods such as the current work on immersed boundaries and porosity from point scans.
There are ...

Re: Controlling maximym number of iterations
Hello,
Yes, code_saturne can build inflation layers, though the handling of "sliding" conditions for faces near to but not adjacent to extrusion layers needs to be improved.
This is not available yet in the GUI (for this reason), but has been available through user-defined functions for a while ...
