### Physics Model

The Finite element simulator is capable to simulate the Incompressible Navier–Stokes equation:

$\frac{\partial \vec{u}}{\partial t} = \nu \Delta \vec{u} - (\vec{u} \nabla) \vec{u} - \nabla p + \frac{\partial \vec{f}}{\partial t}$

With $\nu$ is the kinematic viscosity, $p$ is the pressure, and $\vec{f}$ is the external force density affects on the volume element. Currently the the stationary equation could be solved, with $\frac{\partial u}{\partial t} = 0$
