Hello, I try to import a user-defined library with materials and combustion mechanisme in Ansys Fluent 2022 R2.

I do the following procedure:
In the fluent GUI, I click on File > Read > Scheme... > select my .scm file.

The following error message appears then in the console:

Error: eval: unbound variable
Error Object: material_flumisol_shell

The .scm file is structured like this:

(

(material_flumisol_shell solid

(chemical-formula . #f)

(density (constant . 180.))

(specific-heat (constant . 500.) (polynomial nasa-9-piecewise-polynomial (200. 1000. 1542807. 5735.686 743.4314000000001 0.06124886 -7.495425e-05 4.740278e-08 -1.215476e-11) (1000. 6000. -9000630. 35984.76 726.2905 0.0238426 -4.71308e-06 -3.072811e-10 1.557189e-13) (6000. 20000. -155330700000. 117170100. -33352.98 4.774677 -0.0003297569 1.106924e-08 -1.447104e-13)))

Does anyone know where the problem coul lie ?

Thank you,

If you export a material how does that compare to what you're trying to read in?  

Probably unrelated, but I'd also check the polynomial coefficients: values with very high +/- alternating values may return rubbish when you try and plot it.

Hello,

Thank you for your response.
I solve the problem by copying the materials from the Creat/Edit Material box.
Thank you for your responsivity.
