June 14, 2020, 16:26	Defining expressions	#1
alpha2rock New Member Simar Sethi Join Date: Jun 2020 Posts: 5 Rep Power: 6	I am working on a precipitation problem, and for that I need to define an expression: f=sqrt(C1C2)-sqrt(Ksp) where C1 and C2 are molar concentrations for 2 species. How can I define f? Also, Ksp is a constant that I need to define with units i.e. Ksp=1.110^-11[kmol^2/m^-6] How can I define Ksp? Do I need to use UDF or is it possible using fluent alone? Also I need to use this expression (f) in a UDF. So, how to go about it?
