Hello all,
I am trying to use the SSG RSM to simulate flow in a rod bundle geometry where the pins distort . The mesh in this domain contains tetrahedrals. I have managed to obtain a converged solution but when visualising the pressure field, it looks rather noisy (please see attached picture). This issue is just constrained to the pressure and all the other variables look fine.
I have tried switching between the different IDTVAR schemes, turning on IPHYDR, increasing NTERUP but with no luck. The version of Code_Saturne I am using is 4.0.8.
Any help or advice you can give is much appreciated.
Many Thanks

Re: Noisy pressure distribution
Hello,
In your listing file several mesh quality issue has been detected. Viewing the geometry and its dimensions in the listing file you can try to do a 2D mesh and then extrude (using the CS extrude mesh feature in Mesh options) in the z direction.
Best regards,
Luciano
