Re: plot the pressure over a cylinder in ParaView or EnSight

Hello, Could you ne more specific ? Do you need to map the cylinder surface to a plane or simply view data ? If you need to plot the cylinder to a plane I know there is a new filter for this I'm Paraviz (Paraview + additional plugins) I'm Salome 9.3, but am not sure it is in ParaView itself (and do ...

Re: plot the pressure over a cylinder in ParaView or EnsiGht

Hello,

How is this topic related to this section for Miscellaneous discussion topics about Code_Saturne (development, ...) rather than general usage ?

Regards,

Yvan

Re: Installation_configuration_errors

Hello, The MEDCoupling issue may be due to a change in the MEDCoupling API. You may try to see if you are more sucessful with Code_Saturne 5.0.10, but you may need to switch to Code_Saturne 6.0 beta (or maybe 5.3) for recent MEDCoupling versions. Or if you do not need MEDCoupling, just add --without...

Re: Installation_configuration_errors

Hello, What is the error reported in the main window ? The last errors that appear in the config.log are related to internationalization, but it is hard to distinguish blocking errors from feature detection errors when using only the config.log (which is useful when analyzing the cause of a given er...

Re: Wall_shear_stress_from_post_util

Hello, The efforts in the "global_efforts" example are based on accessing precomputed efforts/stresses, that are computed based on the different term contributions during a time step, so it should be correct with any turbulent model. Note that when computation of efforts/stresses is activated (for e...

Re: scalar temperature

Hello,

Why are you overwriting a solved varoable in a subroutine used for physical properties ? What do you expect it to do ?

Regards,

Re: How to output the laminar and turbulent diffusion coefficients

Hello, scalar_difusivity_id only applies to space varying laminar diffusivity, so if ir us at -1, it means you have a constant laminar diffusivity. Bur that does not provide the turbulent diffusivity. What ylu do have access to is the turbulent viscosity, The diffusivity is computed locally I beleiv...

Re: How to output the laminar and turbulent diffusion coefficients

Hello, I am not sure there is a way to output the diffusion coefficient, except re-applying the formulas used to compute the laminar diffusivity and adding the turbulent diffusivity (which may depend on the turbulent flux model) it in a specific output in cs_user_postprocess_values (cs_user_postproc...

Re: Axisymmetric model and wedge angle

Hello, No, there is no specific recommendation. We typically use 5 to 10 degrees. Be aware that for axy-symmetric cases, we have an issue in the computation of the wall distance (see https://github.com/code-saturne/code_saturne/issues/41 for details) which can affect turbulent wall laws. The angle m...

Re: Build v6.0-beta

Hello, I did not reproduce the error on my side (On a Debian Strech-based sysem, I have not tried on Ubuntu 16.04 LTS). In addition to the log files, there are messages in the console you run the install from, (especially the configure or cmake command used to configure each library) which can be us...
