how to calculate streamlines in matlab?
well i am new in matlab and i am using it to simulate a flow by lattice boltzmann method; i obtained a figure(stream function) and dont know how to obtain the streamlines and values in order to compare my work with a benshmark.
please i need ur help:tell me please how to obtain streamlines from figure's matlab(stream function)
thank you very much
Matlab can draw streamline by itself with the built-in function: streamline. If you give it your velocity field, it can somehow draw a streamline picture.
BUT, in matlab streamline is NOT drawn by calculating stream function but by somehow like integrating a pathline. So if you want a real streamline picture, you should calculate stream function by yourself.
