definiton of volScalarField G(x, y);
im working on a adjustment of a turbulence model.
While doing that i wondered what volScalarField G(x, y); actually does in a mathematical sense. A Definiton like volScalarField S2 = magSqr(symm(fvc::grad(U_))); is clear to me, but i really can not imagine what the "," is doing. (and unfortunately i wasnt able to find any proper syntax description)
Thanks in advance!
The way you've written it, it looks to me like a constructor.
