Help me complete the norton diagram, i cant find my mistakes, im following the steps as in my lab manual

This is the simulink circuit i put three circuits here, the first is the original circuit and the third is the norton equivalent circuit. I couldn't find the direct current source block. I copied the steps as is in my lab manual but im not getting the desired answers. What should i do? In the AC current source i set the frequency at zero and i get Zero as result and when i do set a frequency value i get answers in exponent value. The AC current source is shown in my lab manual. Thanks
