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 193 of file Boundary1D.h.

◆ show()

void show ( const double *  x)
inlineoverridevirtual

Print the solution.

Reimplemented from Domain1D.

Definition at line 197 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 277 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
jGrid point at which to update the residual
[in]xState vector
[out]rresidual vector
[out]maskBoolean mask indicating whether each solution component has a time derivative (1) or not (0).
[in]rdtReciprocal of the timestep (rdt=0 implies steady- state.)

Reimplemented from Domain1D.

Definition at line 282 of file Boundary1D.cpp.

◆ asArray()

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

Save the state of this domain as a SolutionArray.

Parameters
solnlocal 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.

Definition at line 287 of file Boundary1D.cpp.
