[in]

bf

Vector containing source at nodes.

Reimplemented in WaterPorous2D.

BoundaryRHS()

virtual void BoundaryRHS ( const Vect< real_t > &  sf )

build() [1/3]

void build

(

)

Build the linear system of equations.

Before using this function, one must have properly selected appropriate options for:

• The choice of a steady state or transient analysis. By default, the analysis is stationary
• In the case of transient analysis, the choice of a time integration scheme and a lumped or consistent capacity matrix. If transient analysis is chosen, the lumped capacity matrix option is chosen by default, and the implicit Euler scheme is used by default for time integration.

build() [2/3]

void build

(

TimeStepping &

s

)

Build the linear system of equations.

Before using this function, one must have properly selected appropriate options for:

• The choice of a steady state or transient analysis. By default, the analysis is stationary
• In the case of transient analysis, the choice of a time integration scheme. If transient analysis is chosen, the implicit Euler scheme is used by default for time integration.

Parameters

[in]

s

Reference to used TimeStepping instance

build() [3/3]

void build

(

EigenProblemSolver &

e

)

Build the linear system for an eigenvalue problem.

Parameters

[in]

e

Reference to used EigenProblemSolver instance

run()

int run

(

)

Run the equation.

If the analysis (see function setAnalysis) is STEADY_STATE, then the function solves the stationary equation.
If the analysis is TRANSIENT, then the function performs time stepping until the final time is reached.
