Add Delta (R) term
- Add the mysterious
\Delta
(orR
) term - In heat flux balance
- Need closure:
R=-12 \text{Kn} \frac{d s_k}{d x_k} = -12 \text{Kn}\ \text{div}\ s = -12 \text{Kn}\ (\nabla \cdot s)
- Need
\color{blue}{\text{boundary conditions}}
from Rana because of integration by parts with testfunctionr \in \mathbb{R}^d
:\int_\Omega \nabla R \cdot r = -\int_\Omega R (\nabla \cdot r) + \int_\Gamma \textcolor{blue}{R} (r \cdot n)
withR=(\nabla \cdot s)
but this should work nicely.
