Friction modelling

I am trying to formulate expression for the applied torque of motors for a multi link system. If i do not use any friction, then my analytical  model considering lagrangian energy approach to formulate torque is exactly matching to torque calculate by solidworks. But with friction it is not matching. So, can anyone tell me what is the analytical model for friction is uded by solidworks to calculate the torque value.
