ME 702 - Computational Fluid Dynamics - Video Lesson 6
NEW ! (August 2014) Prof. Barba is teaching a MOOC titled "Practical Numerical Methods with Python." Check it out:
http://openedx.seas.gwu.edu/courses/GW/MAE6286/2014_fall/about
*********************************
Practical module: “12 [...]steps to the Navier-Stokes equationsâ€. (Step 5) 2D linear convection. (Step 6) 2D convection. (Step 7) 2D diffusion (Step 8) Burgers’ equation.
*Please note:*
When pseudocode is shown —i.e., something that looks like code, but is not code— remember that it is not meant to be syntactically correct. It is written in a Matlab-esque way, but it is not Matlab code! (This course is taught using Python since 2010.)
