Dear code saturne developpers/users,

I came across to an article about the cooling tower simulation : https://www.code-saturne.org/cms/community/references/Implementation-drift-flux-multiphase-model-fo-3D-draft-cooling-tower

However the article is not available online. Could you share it with us ...

Dear all,

I am wondering if code saturne can handle the water hammer simulation, since generally the incompressible flow solver neglects the pressure variation. I am aware of the compressible flow solver built in Code Saturne since the V4. I am quite curious if it can capture the pressure wave in ...

Hello Yvan,

In the commercial software such as FLUENT, they automatically re-set the "too large" values of the velocity and turbulence scalars like k or epsilon, when the mesh quality is not as high as we wish, to facilitate the convergence of the solution.

Is that possible to do the clipping ...

Dear all,

I am new user of Syrthes to simulate the heating process in a furnace. It is aimed to study the temperature evolution of a cold load introduced in an already heated furnace. So I started a simulation to obtained a steady solution where the furnace and loads are all hot. Then I restart a ...

Thank you Luciano. It is very helpful.

Hello,

Each one of yours CPU's has 10 physical cores and hyperthreading. As Yvan mention you will get the best scalability using

Number of processes 20
Threads per process 1

or

Number of processes 10
Threads per process 2

Also you can run a smaller ...

Hello Yvan,

Here it is my test case with a relatively small mesh.

You can download and run it with .xml file. I didn't use any user-defined routine.

Firstly, I think that the error may occurs because of the face joining of the turbomachinary rotor and stator ...

Hello,

How to do a simple mesh joining and checking the joining results.

In my postprocessing folder, I have
JOINING.case joining.geo results.boundary_zone_id RESULTS.case results.geo results.mpi_rank_id

Using paraview with JOINING.case, I saw only the faces to be joined during the mesh ...

Hello,

Here it is the whole log

Hello,

In most cases, an ERROR postprocessing output is produced to help visualize those faces, but when the error happens at the ordering stage, there is no such output. This error is rare, but has been encountered recently by another person, so I am interested ...

Hello,

Thank you for your reply. Therefore, I can run with

Number of processes 20
Threads per process 2

or

Number of processes 40
Threads per process 1
?

My colleague told me that the CPU has 10 cores, each of which has two virtual threads (not two physical threads). I am wondering if it is ...

Hello

lscpu gives
