Hello CFD Online Community,

I have an issue with changing the unit of an expression in CFD Post.

area()@Outlet

would get me

0.000199688 [m^2]

I want the result to be in mm^2 though. Multiplying by 1000^2 works, but it's still in m^2.

area()@Auslass * (1000^2) * 1[mm/m]

Something like this even changes the result.

Would be glad if somebody ever solved that issue.

Marcel

Why not just change your unit system to custom in the options? Then change length and area to the units you want.

Thanks for the advice, but it won't work for Custom.
If I set Newton Millimeter as the system, it would display them in mm, but not for custom. What do i do wrong?

Try to change the "Solution Units" under "Solver" in CFX-Pre and run CFX-solve again

Keep it unitless. What are you using this for? Just output to something else? If so just call the expression something like this so you know what it is:

area Auslass mm = area()@Auslass * (1000^2) *1[m^-2]
