Re: Wind tunnel modelling, BCs and convergence issues

Hello Yvan,

Thank you very much for your help and explanations, it should be clear to me now !
I checked and the coordinates seems to correspond to the location of the axis' origin.

If I am write, it is only possible to define one Outlet axis, isn't it? Because for my study, the air enters the ...

Re: Wind tunnel modelling, BCs and convergence issues

Hello,

I have a few more questions about the fan subpanel in Code_Saturne 5.0, I would be glad if someone aware of it could help me.

First, I wonder if I have to define another cell-zone just for the fan? Because when I add a fan definition the "zone id" is automatically "0" and I am not sure if I ...

Re: Wind tunnel modelling, BCs and convergence issues

Hello,

First, thank you very much for all your clear answers.

As you advised me I will explore these trails:
- Thinner mesh with hexa parts where it is possible, tetra otherwise.
- Definition of a fan beyond the outlet, I need to get informations about how to do it with the GUI (I guess in C_S ...

Re: Wind tunnel modelling, BCs and convergence issues

My bad ! I made a mistake when I modified the mesh from a previous one for the Vflow BC modelling !

I deleted a surface and now the computation is running ! (see attached for the new mesh that is still very coarse)

Forget about the previous "1st questions", but if it is not bothering you can you ...

Wind tunnel modelling, BCs and convergence issues

Hello,

I am working on a wind tunnel for which I set some Inlet, Outlet, Wall and Symmetry BCs. To avoid modelling the fan, I would like to assign an Inlet BC with a negative volumic flow rate to my outlet (I am not sure it is the more relevant solution).
Besides, I have assigned the same value of ...

Re: Questions about CS & Syrthes coupling

Hi Yvan,

Thank you very much for your quick answer.

Do you have some documentation about this new "internal" coupling please? Maybe it is already in Code_Saturne documentation? I will also watch out news about usage with the graphical interface and Code_Saturne's upcoming version.

For now, I ...

Questions about CS & Syrthes coupling

Hi,

I am new to these software, I have to work on an autoclave's project so I have chosen to simulate the device curing a composite slab. Is it possible to have some precisions about the CS/Syrthes coupling?

- First, I wonder if it is a strong coupling? I mean, are CS and Syrthes exchanging ...
