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...

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,
Ionut

Hi Yvan,

yes, i've allocated it.
I attached the file too.

Thank you,
Ionut

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 e...

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

Hello, I am trying to apply the "field_gradient_scalar" function to the total pressure (iprtot), but in return I receive the following error: Field "total_pressure" with type flag 17 has no value associated with key 37 ("var_cal_opt"). I am using the cs_user_extra_opera...

Thank you Yvan, I figure out the problem of pressure variation, fluent needed more iterations than code_saturne to achieve a similar convergence. In the first figure (https://www.code-saturne.org/forum/download/file.php?id=2719&mode=view) is plotted the "Pressure" variablefrom code_sat...

Hi,

I've uploaded the simulations setup files.
Do I need to upload anything else?

Thank you,
Ionut

Hi, From the same simulation made in Code_saturne, I plotted the "Pressure" along a line that goes on the X axis from the start to the end of the flat plate. The plotted "Pressure" starts from 0.52 and ends at 0.02. I am not sure if the units are Pascals. I tried to validate this...

Thank you very much Yvan.

I will try to find the algorithm from Paraview.
