how can present data of pollutant in ppm, with ansys cfx?
 

i am using ANSYS CFX 14, to simulate the CO2 dispersion in a domain of 500m x 500m and over buildings, my question is about how can present the data contours for CO2 concentrations in ppm (part per million), now i can presentthem only in microgram/m3?
thank you

I suspect CFX does not have the conversion to ppm built in. Then define a new variable in CFD-Post with a CEL expression which does the conversion and then you can view it like any other variabel in CFD-Post.

thank you ghorrocks, i will try this manner
