Hi Ken and others, If I apply these filters to my data set: Data -> Gradient -> Surface Flow, the result (shown in on the information tab of the Surface Flow object) is 0.
With another 3D data set I did not succeed in calculating the flow either. I imagine that I need to do something like: Data set -> Gradient -> Extract Surface -> Integrate Flow How do I extract the correct surface? The extract surface filter description says that in extracts the total outer surface. In my case this results in a nett flow of 0. I have a hollow cylinder and need to calculate the flow over the inner surface and (a part of) the outer surface. How can I achieve this?
