The best I could come up was Needs["VectorAnalysis`"] ContourPlot[ Evaluate[Div@Grad@Sin[Xx + Yy] /. {Xx -> x, Yy -> y}], {x, -5, 5}, {y, -5, 5}] Gabriel On Jan 5, 2012, at 9:00 AM, Szymon Roziewski wrote: > Hello there, > > I am concerning to plot something like that. > > ContourPlot[Divergence[Gradient[Sin[x + y]]], {x, -5, 5}, {y, -5, 5}] > > Plotting divergence of gradient scalar field. > How can I manage to do that? > > Best regards, > Szymon Roziewski
