<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>The energy flows for type 4 do not seem to balance in
my simulation. If I am correct, the change in internal energy (change of output
#7) has to be equal to the net power added (output #11 minus output #4 minus
output #6) times the simulation timestep. In the attached simulation, this sum
doesn’t add up for all timestep. Can anyone figure out the reason?<o:p></o:p></span></font></p>
