Detailed Description

A 2D linear shape function for a 3-noded triangle

phi_1 = 1 - xi_1 - xi_2
phi_2 = xi_1
phi_3 = xi_2
phi_1,xi_1 = -1
phi_1,xi_2 = -1
phi_2,xi_1 = 1
phi_2,xi_2 = 0
phi_3,xi_1 = 0
phi_3,xi_2 = 1

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.
