It seems that you have confused the plots of the parabolas with respect to their equations.
Assuming you have your axes right (x+ point to the right, y+ point up) parabolas of the form "x^2 = 4py" correspond to the 2nd image you attached, while those of the form "y^2 = 4px" correspond to the 1st...
Hi everyone. This is my first post here...
I want to create a numerical simulation in software, to solve the Navier-Stokes equations (Newtonian fluids, compressible and viscous flow) and I have some questions regarding fluids and their dynamics.
(1) The Navier-Stokes equation for the...
