Member Function Documentation

◆ domainType()

string domainType ( ) const

inlineoverridevirtual

Domain type flag.

Since: Starting in Cantera 3.1, the return type is a string.

Reimplemented from Boundary1D.

Definition at line 240 of file Boundary1D.h.

◆ init()

void init ( )

overridevirtual

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.

Reimplemented from Boundary1D.

Definition at line 321 of file Boundary1D.cpp.

◆ eval()

void eval	(	size_t	j,
		double *	x,
		double *	r,
		integer *	mask,
		double	rdt
	)

overridevirtual

Evaluate the residual function at point j.

If j == npos, evaluate the residual function at all points.

This function must be implemented in classes derived from Domain1D.

Parameters

[in]	j	Grid point at which to update the residual
[in]	x	State vector
[out]	r	residual vector
[out]	mask	Boolean mask indicating whether each solution component has a time derivative (1) or not (0).
[in]	rdt	Reciprocal of the timestep (`rdt=0` implies steady-state.)

Reimplemented from Domain1D.

Definition at line 326 of file Boundary1D.cpp.

◆ asArray()

shared_ptr< SolutionArray > asArray ( const double * soln ) const

overridevirtual

Save the state of this domain as a SolutionArray.

Parameters

soln	local solution vector for this domain

Todo:: Despite the method's name, data are copied; the intent is to access data directly in future revisions, where a non-const version will be implemented.

Since: New in Cantera 3.0.

Reimplemented from Domain1D.
