I have created a hydraulic hybrid system in simscape. The model is running smoothly without any errors but the engine block is not giving any power or rpm even at full throttle, hence all the scopes are showing zero reading or close to it. What to do
Does the engine start at no speed? It could be that it is stalling. Start the engine at a higher speed, or add external torque t...
