Interpolation of the gradient of a quantity for discrete particles -- CFD Online Discussion Forums

September 11, 2015, 10:22	Interpolation of a gradient to particles	#1

The naive way of first calculating the gradient of the field by fvc::grad(<some field>) and then applying cellPointInterpolation produces counterintuitive results.
