what is ACA on Meridional surface?
 

for example, pressure ACA on Meridional surface. I am running a compressor simulation. What does ACA stand for?

Thanks!

Area Circuferential Average

CFX makes a new variable whenever you calcuate an average value on a meridional surface, and it prefixes the variable with LCA, ACA, or MCA based on what type of circ. averaging was performed (Length, Area, Mass).
