◆ ComputeF()
|
overridevirtual |
Evaluate F = F(u,v,w) for this line load.
The vector F is set to zero on entry. The function provided by derived classes is called by ComputeQ to perform integration over the domain.
- Parameters
-
U parametric coordinate in volume V parametric coordinate in volume W parametric coordinate in volume F result vector, size = field dim of loadable state_x if != 0, update state (pos. part) to this, then evaluate F state_w if != 0, update state (speed part) to this, then evaluate F
