Source in boundary due to moving wall

Hi all,
I am modeling a physical system in which I am solving Navier-Stokes with one scalar field(c). I have three questions regarding this system. 1. The scalar manifests itself as a source term in NS equation. And the source term is non-linear in scalar. Now, should I define another linearised source term variable: G=f(c) (may contain third and higher derivatives) and do the simulation or should I just include it in terms of c? 2. Scalar has a boundary condition which actually results into a convection equation with source term at moving wall. c(t)+u*c(x)=S(c) Is there a way to implement this in openfoam using current boundary conditions? 3. How good is openfoam in handling third and fourth order derivatives? Thanks and regards, Hrushi |
