#define _ADVECTIONFUNCTIONS_H_

Typedef Documentation

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

Velocity function interface.

Function Documentation

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

Constant flow example.

Return 1.

Parameters
a_pointlocation of the function evaluation
a_velCompvelocity component
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.

Parameters
a_pointlocation of the function evaluation
a_velCompvelocity component
