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

Constructor.

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

Member Function Documentation

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.

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.
