Entering the mechanical and volumetric efficiency of a fixed displacement pump

I want to enter the mechanical and volumetric efficiency values ​​of a fixed displacement pump in a hydraulic system within SIMScape MATLAB. I have activated the mechanical and volumetric efficiency ports from the pump's mass variables, but I have not found a way to enter the efficiency values ​​into those ports... I need help to adjust the efficiency values ​​for the pump

Hi Zeko,

The input ports for the mechanical and volumetric efficiency accept physical signals as the input signal type. To adjust the efficiency values, consider using a constant block and then converting the Simulink signal of the constant block to a Physical Signal using a ‘Simulink-PS convertor’ block.

The outport of the constant block can be connected to the in-port of the Simulink-PS convertor. The outport of the Simulink-PS convertor block can then be connected to the in-port of the mechanical and volumetric efficiency ports, in the fixed displacement block.

The Simulink-PS Convertor block documentation for further reference can be opened from the command window by:

doc(‘Simulink-PS Convertor’)

Hope it helps.
