During my simulation, I need to apply forces to the boundary particles. So I really don't know if the applied force is considered when geting the unbalanced force from utils.unbalancedForce .

Actually, I tried to calculated the unbalanced force by myself. During my calculation, I averaged the resultant force of every particle and divided it by the average contact force. Is that means (f1 + f2 + f3 + ...) / (contact_f1 + contact_f2 + contact_f3 +...). Here fi = sqrt(fi_x^2 + fi_y^2 + fi_z^2) and contact_f1 = sqrt(contact_fi_x^2 + contact_i_y^2 + contact_fi_z^2)?
Is this correct?

Thank you!
