Calculate shape function of node i at a given point s.
- Parameters
-
[in] i Local node label [in] s Point in the reference triangle where the shape function is evaluated
| real_t getDet | ( | ) | const |
Return determinant of jacobian.
If the transformation (Reference element -> Actual element) is not affine, member function setLocal() must have been called before in order to calcuate relevant quantities.
Localize a point in the element.
Return actual coordinates in the reference element. If the transformation (Reference element -> Actual element) is not affine, member function setLocal() must have been called before in order to calcuate relevant quantities.
