Evaluate F = F(u,v) 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 surface
V	parametric coordinate in surface
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
