Computational Physics (CompPhys), Computational Fluid Dynamics (CFD)

I went through Ch.10 of Hjorth-Jensen (2015) and wrote up as many C++ scripts to illustrate all the (serial) PDE solvers: forward, backward Euler, Crank-Nicolson, Jacobi method.

Lid-driven cavity with incompressible, viscous fluid on a 512×512 staggered grid, in CUDA C++11, with finite difference method for 2-dim., unsteady Navier-Stokes equations solver



Compare this with pp. 69 of Ch. 5, Example Applications of Griebel, Dornsheifer, Neunhoeffer.

  1. Congrats for your blog! I found it accidentally and I added it to my bookmarks. I was looking for the lid-driven cavity case in FD coded in OOP-C++ instead of cuda. I want to learn how to write my own cfd codes in multiple CPU’s. Would you have any related material?
