Detailed Description

Outflow boundary conditions for a data structure that has been distributed across ranks

Imposes flows that exit the domain freely at all boundaries, analogous to a domain that extends to infinity in each direction. All ghost cells are identical to their nearest physical cell.

apply()

void ParallelOutflow::apply ( double *  cons, double *  prims = NULL, double *  aux = NULL  )

virtual

Application function.

Applies the Outflow boundary conditions to the ghost cells.

Parameters

[in,out]	*cons	pointer to the conservative (sized) vector
[in,out]	*prims	optional pointer to the primitive vector
[in,out]	*aux	optional pointer to the primitive vector

Applies the Outflow boundary conditions to the ghost cells of subdomains that have an external face along the y dimension.

Parameters

[in,out]	*stateVector	pointer to one of cons, prims, aux
[in]	nVars	number of variables in the cons, prims or aux array

setZBoundary()

Parameters

[in,out]	*stateVector	pointer to one of cons, prims, aux
[in]	nVars	number of variables in the cons, prims or aux array
