Adding latent heat of PCM to FLUENT
 

Hi guys
I'm simulting PCM (Phase Change Material) in Fluent. Do you know how I can add the latent heat of PCM in Fluent?
I defined properties of PCM in UDF for phase change region and solid and liquid zone, but I don't know how I should define latent heat in my UDF.
I added latent heat in the properties of PCM, but according to the articles that defined sensible and latent enthalpy, I think I should define enthalpy variation with temperature in UDF.
Thanks
