◆ _ADVECTIONFUNCTIONS_H_

#define _ADVECTIONFUNCTIONS_H_

Typedef Documentation

◆ AdvectionVelocityFunction

typedef Real(* AdvectionVelocityFunction) (const RealVect &a_point, const int &a_velComp)

Velocity function interface.

Function Documentation

◆ constantAdvection()

Real constantAdvection	(	const RealVect &	a_point,
		const int &	a_velComp
	)

Constant flow example.

Return 1.

Parameters

a_point	location of the function evaluation
a_velComp	velocity component

◆ rotatingAdvection()

Real rotatingAdvection	(	const RealVect &	a_point,
		const int &	a_velComp
	)

Rotating flow example.

At point (x, y, z), set d = (x - 1/2)^2 + (y - 1/2)^2 + (z - 1/2)^2.
If d < 1/2, then return velocity ((y - 1/2)/d, -(x - 1/2)/d, 0).
Otherwise, return velocity zero.
