Constructor & Destructor Documentation

◆ Function_LinearTri()

MOERTEL::Function_LinearTri::Function_LinearTri ( int out)
inline

Constructor.

Parameters
out: Level of output information written to stdout ( 0 - 10 )

Member Function Documentation

◆ Clone()

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

Clone method.

Makes a deep copy of this instance and returns a pointer to it.

Implements MOERTEL::Function.

◆ EvaluateFunction()

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

Evaluate the function and derivatives at a given local coordinate.

Parameters
xi(in) : Local coordinate where to evaluate the function (dimension 2)
val(out) : Function values at xi, dimension 3, if NULL on input no evaluation
valdim(in) : Dimension of val should be 3
deriv(out) : Derivative of functions at xi, dimension 6, if NULL on input no evaluation

Implements MOERTEL::Function.
