ParticipantThe area fraction on a surface where a variable is less than a certain percentage of the average variable can be calculated with the following expressions. A report definition can then be created based on the uniformity expression to monitor the value during the run.
threshold = 0.1
avg = Average(StaticTemperature,[‘outlet’],Weight =’Area’)
areaoutlet = Area([‘outlet’])
uniformity = Sum(IF(abs(StaticTemperature-avg)/avg
