Evaluate the function and derivatives at a given local coordinate.
| 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 |
