shereez234 is on a distinguished road
Code:
fvVectorMatrix UEqn
(
    fvm:ddt(U) 
+  fvm::div(phi,U)
    ==
    fvOptions(U)
)
Hi, so i am trying to understand how this Matrix is implemented in terms of C++ programming.
my question:
is this implementation taking operator overloading in the constructor definition of the fvVectorMatrix class?
Can anyone provide any insight?

Ultimate purpose being trying to implement an equation of this kind in a 2D CFD code i am writing.

Kind regards
M Sereez
