question regarding power simulation

[Musti77]

Hello everyone

I have a tiny question. 

while I am simulating the output power using a wattmeter, the obtained power is appearing as 0 W. 

could anyone inform about the exact problem

note: the simulated circuit is attached below

Thank you in advance..

Hi,

Could you please share the results of simulation at the outputs of components S1, S2, S3?

Best regards
