Tool to compute the force and moment of each particle.
In this approach, since the global force and motion is looked for, the force is computed as: \($ f_a = - m_a \cdot \left( \frac{d \mathbf{u}}{d t} - \mathbf{g} \right) \)$ And the moment as: \($ f_a = - m_a \cdot \mathbf{r}_0 \times \left( \frac{d \mathbf{u}}{d t} - \mathbf{g} \right) \)$
- Parameters
-
forces_f Force of each particle to be computed [N]. forces_m Moment of each particle to be computed [N \( \cdot \) m]. imove Moving flags. - imove > 0 for regular fluid particles.
- imove = 0 for sensors.
- imove < 0 for boundary elements/particles.
r Position \( \mathbf{r} \). dudt Velocity rate of change \( \frac{d \mathbf{u}}{d t} \). m Mass \( m \). N Number of particles. g Gravity acceleration \( \mathbf{g} \). forces_r Point with respect the moments are computed \( \mathbf{r}_0 \).
