Member Function Documentation

template<class T> T Multivac::CTwoCircles< T >::GetDistance (  T  x, T  y )  [inline, virtual]

Returns the distance from a given point to circles. Parameters: x  point abscissa. y  point ordinate. Returns: Distance from (x, y) to circles. Implements Multivac::CInitialCurve< T >.

template<class T> void Multivac::CTwoCircles< T >::GetProjectionOnMesh (  T &  x, T &  y, CMesh< T > &  Mesh )  [virtual]

Returns the closest mesh-point of the projection of (x, y) on the curve. Let A = (x, y). Let B be the projection of A on the curve. Let C be the closest point to B that is on the mesh (included its vertices). On exit, C is returned through x and y: C = (x, y). Parameters: x  first coordinate of the point to be projected. y  second coordinate of the point to be projected. Mesh  mesh. Warning: Undefined function. Implements Multivac::CInitialCurve< T >.

template<class T> void Multivac::CTwoCircles< T >::Save (  string  CurveFile  )  const [virtual]

Saves circles. Parameters: CurveFile  the descriptor of the file where data are saved. Warning: This function doesn't save any point because circles are analytically defined. Implements Multivac::CInitialCurve< T >.

template<class T> void Multivac::CTwoCircles< T >::SetDistances (  CMesh< T > &  Mesh, CLevelSet< T > &  Phi )  [virtual]

Updates the level set function Phi by setting distances to circles. Parameters: Mesh  orthogonal mesh. Phi  level set function defined on an orthogonal mesh. Exceptions: Seldon::WrongCol  attempt to reach a wrong column number. Seldon::WrongRow  attempt to reach a wrong row number. Implements Multivac::CInitialCurve< T >.
