Hi, I have a 3D data set for flow in a pipe. I am using slice to create a 2D slice of the c/s. Then I am am assigning vectors in y and z directions and using evenly spaced streamlines but i cannot see any streamlines. Can someone please let me know how to plot evenly spaced streamlines on a slice? thanks
