Explicit part of the method - HOPBCs based on VCSWeakPressure. For the implicit scheme, we do not extrapolate the advection and rotational diffusion terms, see also S. Dong and J. Shen (2010).

inarray	Holds the vector of previous solutions \( [u^n, v^n, \ldots] \).
outarray	In the implicit scheme, currently an empty array. TODO Don't waste memory here.
time	Holds the new time \( t^{n+1} = (n+1) \Delta t \).

Computes the forcing term for the pressure solve in VCSImplicit::v_SolvePressure(). It uses the weak pressure forcing similar to VCSWeakPressure (coefficient space).

Parameters

fields	Holds the BDF formula of previous solutions \(\sum_q \frac{\alpha_q}{\gamma} [u^{n-q}, v^{n-q}, \ldots]\).
Forcing	Array for the forcing term of the pressure solve. May contain temporary values on input. On output, Forcing = \( \int_\Omega \nabla \phi \cdot \left( \frac{1}{\Delta t} \sum_q \alpha_q \mathbf{u}^{n-q} + \mathbf{f}^{n+1} - N(\mathbf{u})^n \right) \).

Computes the forcing term and advection velocity for ADR solves.

Parameters

inarray	Holds the BDF formula of previous solutions \(\sum_q \frac{\alpha_q}{\gamma} [u^{n-q}, v^{n-q}, \ldots]\).
Forcing	Shared forcing array m_F. Used in pressure and velocity solve. On input, holds temporary values from pressure solve. On output: Forcing = \( - \frac{1}{\nu} \left( \frac{1}{\Delta t} \sum_q \alpha_q \mathbf{u}^{n-q} - \nabla p^{n+1} + \mathbf{f}^{n+1} \right) \).
aii_Dt	\(\frac{\Delta t}{\gamma}\).

Additionally, the advection velocity \( \tilde{\mathbf{u}}^{n+1} \) is computed and handed to the velocity solve via the array m_AdvVel. It is computed as \( \tilde{\mathbf{u}}^{n+1} = \sum_q \frac{\alpha_q}{\gamma} \mathbf{u}^{n-q} - \frac{\Delta t}{\gamma} \left[ \nabla p^{n+1} - N(\mathbf{u})^n - \nu \nabla \times \omega^n + \mathbf{f}^{n+1} \right] \).

overrideprotectedvirtual

Solve velocity system via the ContField::LinearAdvectionDiffusionReactionSolve().

Parameters

Forcing	Holds the forcing term for each velocity component. See output description in VCSImplicit::v_SetUpViscousForcing().
inarray	Unused in this routine. Still, holds \(\sum_q \frac{\alpha_q}{\gamma} [u^{n-q}, v^{n-q}, \ldots] \).
outarray	Holds vector of previous solution \( [u^n, v^n, \ldots] \). Overwritten upon output with new solution [u^{n+1}, v^{n+1}, \ldots].

Additionally, the advection velocity \( \tilde{\mathbf{u}}^{n+1} \) is handed to the velocity solve via the array m_AdvVel. It is computed in VCSImplicit::v_SetUpViscousForcing(). It is defined as \( \tilde{\mathbf{u}}^{n+1} = \sum_q \frac{\alpha_q}{\gamma} \mathbf{u}^{n-q} - \frac{\Delta t}{\gamma} \left[ \nabla p^{n+1} - N(\mathbf{u})^n - \nu \nabla \times \omega^n + \mathbf{f}^{n+1} \right] \).
