Simbelmynë Senior Member Join Date: May 2012 Posts: 548 Rep Power: 15	Hey, I am doing a kinetic energy conservation test for my colocated code and have a question regarding the setup. Mesh: 33x33 I use periodic boundary conditions with a Taylor vortex initial condition. The kinetic energy is dissipated if the initial velocities are too high, but if I make sure that they are low then there is no dissipation of kinetic energy. What may be the cause of this? (some Peclét number violation?) utkunun likes this.
