Re: Problem results

Hello,

Sorry fo my late reply.

Indeed, I had not thought about that. I'll test it.

Thanks again for your help!

Loïc.

Re: Problem results

Hello Brian,

Yes, it's exactly this condition that I want to impose.

Best regards,
Loïc.

Re: Problem results

Hello Brian, Infact, I wish that my upper limit does not affect the flow that occurs on the lower solid wall. This is like placing the upper wall to infinity. In order to achieve this, I impose a sliding wall. I had initially put the component u of the velocity equal to the inlet velocity (1m/s) and...

Re: Problem results

Hello Brian, I run it for 5000 iterations but the problem is still present. I check the balance of conservation of mass and momentum. It appears that suction occurs on the upper face. This explains that the flow doesn't accelerate. The mistake must therefore come from the implementation of the bound...

Re: Problem results

Hello Brian, Thank you very much for your reply. The surface on the top of the flow must be considered as an ideal upper boundary, wall specified shear equaling zero (=zero-vorticity). That's why I chose to impose the u-velocity gradient to zero and the other components of the velocity to zero. For ...

Problem results

Hello, I'm using Code_Saturne version 3.0.3. Currently, I'm trying to simulate the flow on a fat plane. I chose a rectangular domain (2D). The definition of the geometry consists of two joint blocks (using face joinning). I put a wall condition to the bottom wall, symmetries conditions to the side w...

Re: Imposed velocity profile

Hello, I'm using Code_Saturne 3.0.3. I want to impose a non-standard boundary condition : a suction velocity v(x) profile on the upper face of a parallelepiped: v=-0.12/7*Re^(-1/7) This topic and the user guide strongly helped me write the following code: call getfbr ('Farfield',nlelt,lstelt) !=====...

Re: Wall shear stress calculation

Hello, I'm using Code_Saturne 3.0.3. It's been a long time that I'm trying to calculate in simple way the wall shear stress in code_Saturne but without sucess. I have selected "Efforts, tangential" in "Surface solution control". But I can't find the results in my post-processing files. Can you tell ...
