CEL expression
below is my expression:
0.5 [kg s^-1]*step (1-t/1[s])*step (t/1[s]-2) from 0 to 1 sec mass flow rate is 0.5kg/s and then 1-2sec mass flow rate is 0kg/s and then it is 0.5kg/s i want to create expression for this condition: 0-1 sec = 0.5kg/s 1-2 sec = 0kg/s 2-3sec = 0.5kg/s and so on.... |
0.5 [kg s^-1]*step (sin(pi*t/1 [s])) ;)
I haven't used CFX12, so don't know if it's also possible to define this with the 'conditional functions' in CEL. By the way, with your above expression, the flow is always zero |
