My computational data **consists of particle data** , but I would like to **plot the streamlines of the flow field** made up of these particles so that I can see if there are vortices in the details. My result file is a bit large, I have not found ways to upload to here. I have **tried a lot times by using “Delaunay 2D”** ，which will **result in software crashout** on **all computers that I have test.** I want to know is there other approches that can solve my problems? Is there anyone tell me how to operate in details? I will appreciate very much! I can’t wait to know how to operate 🤟 🤝
