January 28, 2015, 07:18	Numerical error at false diffusion case	#1
jpeter3 New Member JPeternel Join Date: Oct 2014 Posts: 19 Rep Power: 12	Hi! I set up this case to check how openfoam deals with false diffusion. However, there appeared a strange thing: in upper right corner there are some serious temperature fluctuations on the area 6x6 cells, independent of the mesh refinement level. The flow has direction of (1,1,0) and domain is 2D. Has anybody an idea why this happens? Photos: https://onedrive.live.com/embed?cid=...A6FoODEJOpoeZc Chears, Jaka
