Hi Rob,nThanks for this advice. How do you see this happening in practice? nFor instance, I managed to created an animation of a xy plot containing 'x-coordinates of nodes' on the y axis. How does it look? - As time progresses, x-coordinate of the interface node increases, until a new node is created (based on the parameters controlling layering) and processes repeats.nIndeed this is a step forward from where I started - which is some quantitative way to visualize the dynamic mesh. So once again thanks for that.nBut do see some way of using report definitions?.Best,nAneeshn
