Hey, I'm very new to programming in C and I'm trying to write a program to simulate the fluid mechanics of a lid driven cavity. The output I get from the program is a set of 2D spatial coordinates and velocity at each point. What would be really useful is a way to output this data as a 2D vector field image, or even a video to show how the velocity changes with time. Does anyone know of any libraries I can use to do this? Preferably one thats as simple as possible to use as I've only been using C for 3 days.
