Hi all,

I'm new in ansys and I have to add some new materials on the fluent database. I know how to add a new material in the set up window but in that way I have to add the material characteristics every time. I'm looking for a way to add new materials and after can select their directly from the fluent database whitin are the others fluid material like air, acetone, etc...

can you help me? Thanks in advance

Thanks AlexanderZ for the rapid answer. I can't create the .scm file, I tried with Notepad and MicrosoftWord. Do you also know how I can set non constant properties? In my case most of the properties are polynomial of the third order. Thanks

Best regards,
Michele

Go to Materials - > create/edit -> user-defined database -> set the name of your new library (any name) -> create one? Yes -> copy materials from case -> select materials, that you want -> Copy -> Save

its my first time to ask and I saw a lot of replies for you Mr AlexanderZ, I know my question is trivial, but how to write the user defined database material file containing material properties as a polynomial function of pressure which is a udf also for pressure inlet
Thanks in advance

[AlexanderZ]

to can define pressure dependent material properties using udf
define_property macro
however, as far as I know specific heat cold not be pressure dependent take it into account
macro for specific heat is DEFINE_SPECIFIC_HEAT

for more information and example read Ansys Fluent Customization manual
