Member Function Documentation
◆ getDet()
| 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.
◆ getLocalPoint() [1/2]
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.
◆ getLocalPoint() [2/2]
Localize a point in the element.
Return actual coordinates where s are coordinates in the reference element.
