March 12, 2021, 03:52	How to calculate the divergence of velocity	#1
Proxima New Member Wang Yanqing Join Date: Mar 2021 Posts: 3 Rep Power: 5	Hi, i want to get the divergence of velocity field, and i have calculated the gradient of velocity. When using equation DuDx+DvDy+DwDz to get divergence i find it is not equal 0 in incompressible fluid. Anyone can help me. Thank you!
