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.)

Does anyone know where the problem coul lie ?

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.

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