Detailed Description

Describes an "S" evolution law.

Constructor & Destructor Documentation

Law_S::Law_S ( )

Constructs an empty "S" evolution law.

Member Function Documentation

void Law_S::Set ( const Standard_Real  Pdeb,
const Standard_Real  Valdeb,
const Standard_Real  Pfin,
const Standard_Real  Valfin 
)

Defines this S evolution law by assigning both:

  • the bounds Pdeb and Pfin of the parameter, and
  • the values Valdeb and Valfin of the function at these two parametric bounds. The function is assumed to have the first derivatives equal to 0 at the two parameter points Pdeb and Pfin.
void Law_S::Set ( const Standard_Real  Pdeb,
const Standard_Real  Valdeb,
const Standard_Real  Ddeb,
const Standard_Real  Pfin,
const Standard_Real  Valfin,
const Standard_Real  Dfin 
)

Defines this S evolution law by assigning.

  • the bounds Pdeb and Pfin of the parameter,
  • the values Valdeb and Valfin of the function at these two parametric bounds, and
  • the values Ddeb and Dfin of the first derivative of the function at these two parametric bounds.
