danslecul is on a distinguished road
Hi I've been given a 3d cylinder case file and trying to meausre the far field sound generated by the surface, so far though just simulating the flow is not giving the desired results to allow me to measure the acoustics. I am trying to run a DES simulation but the results appear to be more laminar with no vortex shedding in the cylinder wake, any ideas where I could be going wrong?
