i try to setup parametric for air change value as follow:
INPUT LOADS ..
PARAMETER PAIR = 0.2 ..
....
AIR-CHANGES/HR =PAIR TIMES 2.0
END ..
COMPUTE LOADS ..
COMPUTE SYSTEMS ..
COMPUTE PLANT ..
PARAMETRIC-INPUT FOR LOADS ..
PARAMETER
AIR-CHANGES/HR =1.0 ..
END ..
COMPUTE LOADS ..
COMPUTE SYSTEMS ..
COMPUTE PLANT ..
STOP ..
It runs 2 times but the second is not meet new air-change/hr value. what's wrong inside my syntax. Thanks
