subroutine clsyvt ( )

Parameters

[in]	nvar	total number of variables
[in]	nscal	total number of scalars
[in,out]	icodcl	face boundary condition code: 1 Dirichlet 3 Neumann 4 sliding and $\vect{u} \cdot \vect{n} = 0$ 5 smooth wall and $\vect{u} \cdot \vect{n} = 0$ 6 rought wall and $\vect{u} \cdot \vect{n} = 0$ 9 free inlet/outlet (input mass flux blocked to 0)
[in]	dt	time step (per cell)
[in]	rtp,rtpa	calculated variables at cell centers (at current and previous time steps)
[in]	propce	physical properties at cell centers
[in]	propfa	physical properties at interior face centers
[in]	propfb	physical properties at boundary face centers
[in,out]	rcodcl	boundary condition values: rcodcl(1) value of the dirichlet rcodcl(2) value of the exterior exchange coefficient (infinite if no exchange) rcodcl(3) value flux density (negative if gain) in w/m2 or roughtness in m if icodcl=6 for the velocity $(\mu+\mu_T) \gradv \vect{u} \cdot \vect{n}$ for the pressure $\Delta t \grad P \cdot \vect{n}$ for a scalar $cp \left( K + \dfrac{K_T}{\sigma_T} \right) \grad T \cdot \vect{n}$
[in]	velipb	value of the velocity at $\centip$ of boundary cells
[in]	rijipb	value of $R_{ij}$ at $\centip$ of boundary cells
[out]	coefa	explicit boundary condition coefficient
[out]	coefb	implicit boundary condition coefficient
