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".

Luciano

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.

Luciano.

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.

Luciano

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...

Hello, The line "call getfbr('2 and x < 0.01', nlelt, lstelt)" is used for the selection of boundary faces satisfying a specific criteria. The criteria is that belongs to a group of face number/color "2" and the coordinates of the face centers x-coordinate "x<0.01". In ...

Re: Internal coupling spurious velocity
Hello Yvan, Thanks for the suggestion, I will try it. It is like to set a penalization for this term In the solid region. Another workaround that I found is to set the same density in both, fluid and solid, and in order to maintain the volumetric heat capacity in the solid part I have set the heat c...

Re: Internal coupling spurious velocity
Hello Yvan, Thanks for your quick reply. I have tried your suggestion but I get the same behavior with some iterations in the velocity field in the solid part. In the setup.log appears the text "Fluid-solid mode (disable dynamics in the solid part)" Regards, Luciano setup.log run_solver.log

Internal coupling spurious velocity
Hello, I'm running in CS 6.0.4 a simple example using the internal coupling feature, but when setting different densities (rho_air=1, rho_solid=100) spurious velocities appears at the solid region as seen in the picture. The densities and temperature are constant and the gravity is turned on. If gra...
