Natural convection (couple Syrthes & code_saturne)

[Sven]

Hello,

I found an article about using Syrthes in combination with code_saturne for simulating the heat transfer of a passive cooler and I want to give it a try on an university project. If I understand it right, Syrthes is for simulating the heat transfer insite of the cooler and code_saturne for the convection at its wall.

Now I installed the CAELinux 2011 which comes with saturne 2.0.2 and many other tools for simulating those things and I wonder how I can combine it with Syrthes. I downloaded the latest Syrthes Version (4.1.1) and tried to find out how to install it right.

Looking at the setup.ini of the Syrthes-Installation, there are a couple of options to consider.

Code: Select all

#--------------------------------------------------------
# SYRTHES for coupling with Code-Saturne (optional)
#--------------------------------------------------------
# Warning : MPI installation must be defined before
#
#ple USE=no
ple USE=yes   PATH=/.../saturne/opt/libple-1.0/arch/MY_ARCH
#
syrthescfd INSTALL=no
#
#

Do I have to change the PATH? I can't find a path like this in the saturne installation. And what about the MPI? How do I define it before? What is the syrthescfd?

Is it necessary to change something in the saturne installation/options to combine the two programs?

To get an idea of what I'm trying to do, look at the picture I attached. This comes from a COMSOL-Simulation.

The next question is: How do I get this Software run? How to get the solution starting with the 3D-CAD-Files?

Thank you,
Sven

Hi Sven,

I recommend to you to use the last version of code_saturne with the last version of Syrhtes. I know that the coupling between code_saturne and Syrthes is easiest after the version around 3.0 of code_saturne. You can see the tutorial below to see the detail for coupling code_saturne with syrthes:

I hope it will help you.
