hello. anyone expert in simmechanics. i need an urgent help. i am doing dynamic analysis of an engine.

in my model diagram i have modelled a simple engine and i am giving initial velocity to my crank. no other body actuator or friction block is used in my model. when i am giving my crank initial velocity of 1000 deg/sec. the mean speed of my crank as given by the joint sensor is 1000 only. but when i am giving my crank initial velocity of 10000 deg/sec. the mean speed of my crank increases with time. how this happening. energy has to be conserved of a system. but in mine model its increasing. please help. i can also mail u my model diagram too... i am making my final year project. so please help.

one thing to add up. i am using joint initial condition to give my crank an initial velocity.

I am deeply sorry and i have acknowledged that I was so wrong to mark my question as urgent. That was my first question in this community so please forgive me.
