Hello,

I was reading your last listing file and note the following things. Issue has been detected during the mesh quality check, also you have a message that all your cells have a mass source term, it is correct?

At the outlet you are using a free inlet/outlet BC without a external head loss ...

Hello,

You can find information about the turbulence model and wall functions in both, the theory and users guide of CS. Also, you can check the files(cs_wall_functions.c and cs_wall_functions.h) about the implementation of this laws.

Additionally, you are solving a heat transfer problem so you ...

Hello,

May be this old post could help you http://code-saturne.org/forum/viewtopic.php?f=2&t=67.

I think that you should try first to couple the two fluid domains and then these with syrthes,

Hello,

What data/information do you need to exchange through the interfaces solid-fluid and fluid-fluid?

Hello,

I really don't know in detail where the convergence it is verified but you can check the the file /base/cs_equation_iterative_solve.c and the documentation in http://code-saturne.org/doxygen/src/cs__equation__iterative__solve_8c.html .
Also, in the theory guide there are information about ...

Hello,

You can check it in the user manual (search for kivisl, diffusivity or conductivity)

Also check the cs_user_parameters.f90 file in the SRC/EXAMPLE directory in order to view how to access.

EDIT: Sorry..you ask for the C function and I have wrote about the fortran ...

Hello,

I think that you want to scale the geometry in the "z" direction. You can use the filter "Transform" for that.

Hello,

I was checking the source code (cs_mesh_bad_cells.c) of the offset criterion in CS 4.0.0 and CS 4.0.6. This criteria has changed from
CS 4.0.0

of_n = fabs(_DOT_PRODUCT_3D(v_of, v_n));

to
CS 4.0.6

of_n = _MODULE_3D(v_of) * _MODULE_3D(v_n);


Also, you can view the change in the ...

Hello,

I run your script and did the check mesh in CS 4.0.2 and get 0% of bad cells with the offset criterion and 2% (21000 cells) of bad cells with Least-Squares Gradient criterion over 1.33 Mcells. But, if you change Netgen 3D by 3D Extrusion in the solid meshes you will get a mesh of 650 Kcell ...

Hello,

In the theory guide of CS you can find de definition of the Cell Offset quality criteria and the geometrical parameters involved.

Are you sure that your internal mesh is fully tetrahedral? Because it appears to be an 3D ...
