Constructor & Destructor Documentation

MOERTEL::Function::Function ( int  outlevel, MOERTEL::Function::FunctionType  type  )

inline

Constructor.

Constructs an instance of this base class.

Parameters

outlevel	: Level of output information written to stdout ( 0 - 10 )
type	: Function type

MOERTEL::Function::Function ( const MOERTEL::Function &  old )

inline

Copy-Constructor.

Makes a deep copy

Parameters

old	: Instance to be copied

Member Function Documentation

virtual MOERTEL::Function* MOERTEL::Function::Clone ( ) const

pure virtual

Clone method.

The derived class implementing this virtual method is supposed to make a deep copy of itself and return a pointer to the copy.

Implemented in MOERTEL::Function_DualBiLinearQuad, MOERTEL::Function_BiLinearQuad, MOERTEL::Function_ConstantTri, MOERTEL::Function_DualLinearTri, MOERTEL::Function_LinearTri, MOERTEL::Function_DualLinear1D, MOERTEL::Function_Linear1D, and MOERTEL::Function_Constant1D.

Referenced by MOERTEL::Segment::SetFunction().

virtual bool MOERTEL::Function::EvaluateFunction ( const MOERTEL::Segment &  seg, const double *  xi, double *  val, const int  valdim, double *  deriv  )

pure virtual

Evaluate the function and derivatives at a given local coordinate.

Parameters

xi	(in) : Local coordinate where to evaluate the function
val	(out) : Function values at xi
valdim	(in) : Dimension of val
deriv	(out) : Derivative of functions at xi

Implemented in MOERTEL::Function_DualBiLinearQuad, MOERTEL::Function_BiLinearQuad, MOERTEL::Function_ConstantTri, MOERTEL::Function_DualLinearTri, MOERTEL::Function_LinearTri, MOERTEL::Function_DualLinear1D, MOERTEL::Function_Linear1D, and MOERTEL::Function_Constant1D.
