do you have some code examples of non ideal adiabatic method of stirling engine in MATLAB?

Hello community, I want to plot all the graphs of Stirling engine in MATLAB (the volume variations depending on the crank angle, the pressure variation depending on the crank angle, Pressure-Volume diagram,.....) using the non ideal adiabatic method, but when I run the code it doesn't give me the sinusoidal movement, I don't know why, can you help me please??

You can see a Stirling Engine example in Simscape here: Gamma Stirling Engine
