Re: Velocity at the wall

Hi Yvan, thank you for helping me. I made another simulation in Code_Saturne using the k-omega SST turbulence model, ensuring that the no wall function it was selected, my mesh y+ is smaller than 1. The mesh generation I made in ICEM CFD. If I process the results in ParaView the velocity at the wall...

Velocity at the wall

Hello, I made a steady state simulation using the k-omega SST turbulence model on an asymmetric diffuser geometry. I placed monitor points, from y = 0 to the center of the geometry at a given section, and it seems that code saturne is calculating a velocity at the wall too (at y = 0 I have a velocit...

access velocity x,y,z

Hello, I need to access the velocity, on x, y and z direction, from inside the cs_wall_functions_2scales_log, "cs_wall_functions.h" file. I assume the variable "vel" is the velocity in the x direction, it is correct? From doxygen documentation, I understood that I should use this "cs_real_3_t *cvar_...

wall function parameters

Hello, I'm trying to modify the 'cs_wall_functions_2scales_log' wall function. I'm having some troubles to understanding some of the parameters inside the code. Could someone help me to understand the meaning of them, formulae would be great too. * \param[out] iuntur indicator: 0 in the viscous subl...

Re: zero velocity at the wall

Hi,

I thought that if I don't need them I could comment them. I didn't want to use more memory if is not needed for the software.

I uncommented them and now is working.

Thank you,

zero velocity at the wall

Hello, I am trying to set from "cs_user_boundary_conditions.f90" zero velocity at the wall. I am using this code: call getfbr('PLATE', nlelt, lstelt) do ilelt = 1, nlelt ifac = lstelt(ilelt) rcodcl(ifac, iu, 1) = 0.d0 rcodcl(ifac, iv, 1) = 0.d0 rcodcl(ifac, iw, 1) = 0.d0 enddo I get this error: SIGS...

Re: Code_Saturne_Automatic scheme and Low_Re_models Convergece

Hi

What kind of scheme it is used for Pressure in the 'Scheme' tab from the 'Equation Parameters' menu?
I attached a picture too. showing the issue that I have.

Thank you,
Ionut
