Currently am designing buck converter and i need to find the the RMS and average values of my waveform.
i found RMS and Mean models. but whenever i key in the initial input, the output the mean or RMS will be initial input values.

can someone guide me along

This seems to be a parameterization issue. It must be ensured that one cycle of simulation has completed to get the correct results. The block uses a running average window. First cycle of the simulation the output will be the specified initial condition.
