I am trying to simulate a simple 3-phase circuit with RL-load in HYpersim using state pace model of the circuit. I found out the state-space model from the transfer function of the circuit and substituted the values of A,B,C and D matrix in the state space block. But the output current and voltage waveforms correspond to open circuit characteristics.

Is the state space matrix determination in Hypersim same as the conventionall state space modelling approach?

If so, what does the matrix D1 in the state space model imply?
