[TRNSYS-users] Problem with type 60

[David Bradley]

Claire,
 The degree to which the tank stratifies is the result of the tank 
geometry and the inputs. If you have a small tank and very large 
flowrates going into and out of the tank then the stratification will 
disappear. If you are putting low flow rates of very hot or very cold 
water into the tank, then stratification should begin to appear. If you 
would like to send me your input file, I can take a look at it for you 
and see if I can find the cause.
Kind regards,
 David
