How to define multipy conditions in Fluent named expression?

Scar123111 · February 24, 2020, 18:22

Hi,
I know how to use basic conditional function for single conditon in Fluent, for exemple: IF(x>0,1,0). However, I don't know how to define multiple conditions. For exemple, I want IF(x>0 && y>0 && z>0,1,0) but "&&" doesn't work in Fluent expression language. Do you guys have an idea about how to solve that? Does anyone know how "AND" , "OR" and "NOT" function work in Fluent named expression? I can't find any information about these founctions online. Thanks!

In Fluent's expression language, you have to do it like this

AND(expr1, expr2)

Since the output is true or false, IF is not required. You can nest these.
