Hi, Fluent users:

I want to use UDF to define temperature-dependent specific heat in Fluent. Which udf should I use? I thought of DIFINE_PROPERTY. But in the manual, it doesn't mention specific heat can be defined. Thank you for your help in advance!

For defining specific heat you should use a different macro. It should be defined a Define_Specific_heat. You can find more details in the following pages:
