ERROR in user-defined database materials
 
I'm trying to run a user-defined database but Fluent says : Error: GENERAL-CAR-CDR: invalid argument [1]: improper list Error Object: eau-usee

Here is the user-defined database :

(eau-usee fluid (density (constant . 999.7)) (specific-heat (constant . 4193)) (thermal-conductivity (constant . 0.528)) (viscosity (constant . 0.00131)) (molecular-weight (constant . 18.1)) )

(fluide-caloporteur fluid (density (constant . 998.2)) (specific-heat (constant . 4182)) (thermal-conductivity (constant . 0.6)) (viscosity (constant . 0.001003)) (molecular-weight (constant . 18.1)) )

(inox solid (density (constant . 7850)) (specific-heat (constant . 486)) (thermal-conductivity (constant . 16)) )

What is the problem ? Thanks

Julien

Hi!! I had that problem but I discovered that you need to set another () for all that code you wrote, e.g.

(

(Aluminio solid

(chemical-formula . Al)

(density (constant . 3000))

(specific-heat (constant . 871))

(thermal-conductivity (constant . 202.4))

(formation-entropy (constant . 164448.08))

) )

Thanks! Now it works

Hi! I want to know what is the "text command" to copy materials from user-defined database. "define materials copy" don't works. Thanks,

Julien
