I am trying to analyze here how streamlines and pathlines look like from my simulation data. For streamlines: I am using Mask points filter on some physics variables to choose seeds at every time step. Now when I try to use particlepath filter with same mask points(only intial), in the next time step all points are disappeared. So I couldn’t get pathlines for those selected seeds. Could you please help me to resolve this issue ?
Please tell me how to save mask points to the .csv file. I tried to save them in the usual way but it only shows save option for input data but not mask points.
