code_saturne User's Forum

Helo Cyprien and Yvan, Thank you so much for your message Cyprien, it helped me a lot ! To solve the omniidle issue, I read in the README that we can add at the configure command : ./configure --with-salome=$SALOME_ROOT_DIR OMNIIDL=$SALOME_ROOT_DIR/INSTALL/omniORB/bin/omniidl It solved my problem. ...

Hello, Yvan,

Thanks for your reply. I hope the fix will be useful to other users too.

Hello all, I am using code_saturne 8.2 and trying to perform a simple VOF simulation. I am trying to write a user expression through the GUI for a source term in the momentum equation: """ if (t<1.) { Su = 0.; } else if (t<2.) { Su = rho * 9.81 * (t-1.); } else { Su = rho * 9.81; } Sv...

Hello Yvan, Thanks a lot for taking the time and for looking into this. My intention was actually to have an emissivity on the outer face, in order to avoid computing also the solid and the surrounding air... I hadn't noticed the warning on the wall temperature, I will look into it more in detail. I...

Hello Yvan,

Thanks a lot. I understand. I wish you "bon courage".

Kind regards,
Theo

To see the effect of radiation on.the wall, I think only the thermal BC type involving a balance computation at the wall will/should work for this. I agree with you that this should be possible without including a thermal radiative heat transfer model for the gas flow. However, I am not familiar wi...

Bonsoir Yvan, Thanks a lot for your quick reply! I have prepared a simple case with a circular pipe (inlet + outlet + wall), of radius 10mm and length 400mm. There is a flow of hot gas, entering at 900°C with 10m/s. There are 3 cases inside, the only difference being in the boundary condition at the...

Hello code_saturne users, I have a question regarding how to set up a boundary condition with radiation+convection on an external wall. I'm trying to simulate a hot gas flow through ducts in Code_Saturne. I was wondering how to setup a boundary condition on the wall that combines: * a heat transfer ...
