I am new to openfoam and was just trying to understand icofoam code.
in the follwing portion of the code
set up the pressure equation
fvm::laplacian(rUA, p) == fvc::div(phi)
for setting pr eqn divergence of phi is used. if phi is scalar field(inner product of face velocity and surface area normal) then how can its divergence be defined ?
thanks in advance.
Thanks for ur kind response.
