Detailed Description

A class for solving advection-diffusion problem.

Eq: du/dt + v*du/dx = D*d²u/dx² u - amount v - velocity D - diffusion coefficient

Member Function Documentation

setVelocity()

auto setVelocity ( double  val ) -> void

inline

Set the velocity for the transport problem.

Parameters

val	The velocity (in m/s)

setDiffusionCoeff()

auto setDiffusionCoeff ( double  val ) -> void

inline

Set the diffusion coefficient for the transport problem.

Parameters

val	The diffusion coefficient (in m^2/s)

setBoundaryValue()

auto setBoundaryValue ( double  val ) -> void

inline

Set the value of the variable on the boundary.

Parameters

val	The boundary value for the variable (same unit considered for u).

initialize()

auto initialize

(

)

-> void

Initialize the transport solver before method step is executed.

Setup coefficient matrix of the diffusion problem and factorize.

step() [1/2]

auto step	(	VectorRef	u,
		VectorConstRef	q
	)		-> void

Step the transport solver.

This method solve one step of the transport solver equation, using an explicit approach for advection and total implicit for diffusion. The amount resulted from the advection it is passed to diffusion problem as a "source".

Parameters

[in,out]	u	The solution vector
	q	The source rates vector ([same unit considered for u]/m)

step() [2/2]

auto step

(

VectorRef

u

)

-> void

Step the transport solver.

Parameters

[in,out]

u

The solution vector
