- see whether deltaP * Q gives you the right pump power. You may use a pressure sensor for the pressure increase over the pump and a flowrate sensor for Q.
- access Simscape result AFTER the simulation using command line and plot. See this documentation page for more info: https://www.mathworks.com/help/physmod/simscape/ug/log-and-plot-simulation-data.html
How to access Hydraulic Power value from Pump block?

I am designing a wheel loader system in which I have to analyse efficiency.
My approach so far is to calculate such efficiency with the power induced by the Fixed-Displacement Pump and the power developed by the Mass.
I've found two ways to obtain my Mass Force and Speed (mechanical sensors and Probe) so I can calculate it power.
However, even though I can see my pump Hydraulic Power in the Simscape Results Explorer, I can't manage to extract it for calculations with sensors or a Probe.
I am using 2020a version.

Hi Lucca,
The Probe right now only works with quantities that is visible in the "variables" tab of the block, so you are right you won't be able to measure that directly. I can think of two possible solutions:
Hope this helps.
