weird results in CFX post
 

Dear all:
i simulated a mixture(H2 and Argon) flowing through a domain. in the inlet boundary, i set 0.324150312 as H2 mass fraction.
but after simulation was finished, i viewed mass fraction at inlet in CFX post, from the function calculator no matter i use areaAve, massflowAve, massflowAve, maxVal or minVal, the H2 mass fraction result is 0.1486.
but when i mapped the inlet with mass fraction colour in 3D viewer, the legend range is still 0.324150312. why function calculator gives me wrong results?
is there anyone who can tell me?
kind regards
