Re: A tutorial on cavitation two-phase flow modeling
Hello, The error log is telling you that Some boundary condition definitions are incomplete or incorrect. and For details, read the end of the calculation log, or visualize the error postprocessing output. Did you check which BC is not defined? My recommendation is to use the lasted production versi...

Re: A tutorial on cavitation two-phase flow modeling
Hello, I guess you set up the case on a Text-User Interface and with modification in the source code, not? No, I am using the GUI to set up the case and most of the BC's. The user files are used to define the void fraction at the inlet and the outlet pressure. What version of CS are you using? Could...

Re: A tutorial on cavitation two-phase flow modeling
Hello, I did a simple test using the cavitation model some time ago, but I didn't complete a full validation test. I just update the test case for CS 6.0.4. I upload the necessary files (data, mesh, user files) and also some additional documents about the test. I hope this helps you as a starting po...

Re: Which file is read in restart for velocity and pressure?
Hello,
Did you check the user guide?
In section 3.9.3.7 Variables saved to allow calculation restarts, you have a detailed description of the saved files in the checkpoint directory and also the variables saved in each file.
Regards,
Luciano

Re: Schmidt number in code saturne
Hello,
Did you check the theory guide of CS? It appears several times.
Also, you can search in the source code, the turbulent schmidt key for scalars is "ksigmas".

Re: Axail fan modelling usin cs_fan.h
Hello Yvan,
Do you have any references for the implementation of the axial fan model? Because there are different alternatives depending on the blade, fan and hub radios. Also in the 2D modeling, there is weighting with the thickness and radios.
Thanks in advance.

Re: import meshes from OpenFOAM
Hello Kumar,
I'm using the foamMeshToMED converter mentioned in the previous post. I'm using it to convert snappyHexMesh and CfMesh meshes to CS without any problem. Boundary conditions and cell zones are correctly transferred to CS.
It's compiled with OF 4.x.

Re: Hagen–Poiseuille flow comparison between CFD and Theory
Hello If you set an average/constant inlet velocity of 0.01m/s you will never have a maximum speed lower than this value (0.0074778) due to mass conservation, near the wall the velocity is lower than 0.01, so in the center has to be greater than 0,01. The theory for 2D flow between parallel flat pla...
