November 17, 2015, 19:05	Equations solved by potentialFoam	#1
t.oliveira Senior Member Thomas Oliveira Join Date: Apr 2015 Posts: 114 Rep Power: 13	The OpenFOAM Extend Wiki explains that the equations solved by potentialFoam are: $\nabla \cdot \vec{U} = 0$ $\nabla^2 p = 0$ Is that really what potentialFoam does? (I wasn't able to figure out by reading the file potentialFoam.C) If it is, why does it make sense? I understood that the correct way to solve for the pressure in a potential flow field would be to first solve $\nabla^2 \phi = 0$ , from $\phi$ compute $\vec{U} = \nabla \phi$ , and then compute using Bernoulli's principle. Thanks!
