Detailed Description

A class for axisymmetric stagnation flows.

Definition at line 507 of file StFlow.h.

Member Function Documentation

void eval	(	size_t	jg,
		doublereal *	xg,
		doublereal *	rg,
		integer *	diagg,
		doublereal	rdt
	)

virtual

Evaluate the residual function for axisymmetric stagnation flow.

If jpt is less than zero, the residual function is evaluated at all grid points. If jpt >= 0, then the residual function is only evaluated at grid points jpt-1, jpt, and jpt+1. This option is used to efficiently evaluate the Jacobian numerically.

virtual void init ( )

Initialize.

This method is called by OneDim::init() for each domain once at the beginning of a simulation. Base class method does nothing, but may be overloaded.

Definition at line 82 of file StFlow.h.

void setThermo ( IdealGasPhase & th )

inlineinherited

virtual void _getInitialSoln ( doublereal * x )

inlinevirtualinherited

Reimplemented from Domain1D.

Definition at line 125 of file StFlow.h.

References StFlow::T_fixed(), and StFlow::Y_fixed().

void _finalize ( const doublereal * x )

virtualinherited

In some cases, a domain may need to set parameters that depend on the initial solution estimate.

In such cases, the parameters may be set in method _finalize. This method is called just before the Newton solver is called, and the x array is guaranteed to be the local solution vector for this domain that will be used as the initial guess. If no such parameters need to be set, then method _finalize does not need to be overloaded.

size_t bandwidth ( )

inlineinherited

Set the Jacobian bandwidth for this domain.

When class OneDim computes the bandwidth of the overall multi-domain problem (in OneDim::resize()), it calls this method for the bandwidth of each domain. If setBandwidth has not been called, then a negative bandwidth is returned, in which case OneDim assumes that this domain is dense – that is, at each point, all components depend on the value of all other components at that point. In this case, the bandwidth is bw = 2*nComponents() - 1. However, if this domain contains some components that are uncoupled from other components at the same point, then this default bandwidth may greatly overestimate the true bandwidth, with a substantial penalty in performance. For such domains, use method setBandwidth to specify the bandwidth before passing this domain to the Sim1D or OneDim constructor.
