Re: Artefacts

Hi, So, as per your suggestion, I have tried the green-gauss with least-squares gradient face values gradient reconstruction type with automatic extended cell neighbors option. I have increased the sweep value from 5 to 10 for pressure. However, the simulation has diverged at a very early stage afte...

Re: Artefacts

Hi Thank you for your reply, The simulation has been converged for the LES simulation (restart with RANS simulation) or worked well in other words if we used the code-saturne V6.0.0. I have used the least square gradient scheme. But we noticed that there are mesh artifacts in the results. However, t...

Re: Artefacts

Hi, Thank you for your reply. As per your suggestion I have checked the mesh quality criteria and some non_ortho mesh has been detected (please find the attached image). Additionally I have tried the simulation with a blending factor of 0.95 for velocity (second order linear upwind) and with pressur...

Artefacts

Hi I am trying to solve the large eddy simulation for a vertical cylinder, which has two-inlet boundary conditions. The issue with the simulation is there are some artefacts (possibly due to the mesh) throughout the cylinder in turbulent kinetic energy and velocity calculation. I have tried the simu...
