Actually i have the mean diameter and spread parameter which is to be used in the simulation. i have diameter range from 1um to 300um. and i only know the total mass of droplets and no of droplets from ansys fluent summary.
I am unable to figure out how to use the ANYS GUIDE RELATION of yd.

I am just using the values that i know and plotting yd and diameter from it like the curve above. But I don't know how to extract or get the points (Mass Fraction of droplets larger than certain diameter).
Kindly guide me through this.
