Talk:Velocity gradient

Hi, I think the structure of this article should be reconsidered. Velocity gradients also play an important role in continuum mechanics (http://continuummechanics.org/cm/velocitygradient.html). The article otherwise is just an example from fluid dynamics.

just some more sources
"On the identification of a vortex" by Jeong and Hussain (1995, see https://doi.org/10.1017/S0022112095000462) and "An objective definition of a vortex" by Haller (2005, see https://doi.org/10.1017/S0022112004002526) both use the velocity gradient and/or derived tensors for identifiying vortices. — Preceding unsigned comment added by 2003:C3:43E4:2C19:DC70:9569:3348:2F22 (talk) 09:49, 5 May 2018 (UTC)
