Hello, could you share the example with the mesh and everything?

Well, I am no able to put any value in time step factor.

Well I checked couple scalar in solid zones, but until I used joining faces in mesh tab, there was no heat transfer. But I have no option rough wall even if I tick turbulence. Ok but coudn't I enter some very small value for specific heat capacity to obtain steady state solution faster? If I try tha...

Thanks for reply.

And how do I prescribe coupling between fluid_solid boundaries? Is it enough just have merged mesh or use face joining?

Also, why the rough wall option is greyed out?

Why there is no option for "steady state" soluton? Code_saturne calculates only transient?

Hello,
I am trying to simulate something similar, but I cannot prescribe physical properties for the fluid domain.

Also, there is no option for solid-fluid interface.

Hello,
I looked into the documentation but it is quite overwhelming. Isn't there some example with mesh and defined groups, where is computed some user field and I could just run it?

I tried the vorticity example to try if I could even make work any user field.

For example velocity in inlet. Runaway computation: At least one field exceeded allowed bounds (see log). I was searching for "cs_field_gradient" , but couldn't find any full example with mesh. I tried for example put this code into cs_user_extra_operations.c but it doesnť work. https://ww...

Thanks for reply. I know that I can get heat flux at the boundary, but how to obtain heat flux and temperature gradient in the whole volume domain? And why the temperature on the volume domain is little less than on the boundary? I tried to use consistent units, but code saturne doesn't like for exa...

Hello, I am trying to simulate simple steel tube with prescribed temperature. I would like to know how to get temperature gradient, and later heat flux. I read that I have to create cs_user_extra_operations and put it into SRC, but I don't know what code to write. Every time I find some example, it ...
