Hi,nIn ansys fluent, how can we use a a tabulated data to describe the real fluid properties instead of the expression equations in UDRGM?nI found this method in a research work which Ansys Fluent v19 was used in it, whilst I was wondering how to Implement this approach. I didn't find any interface to import a tabulated data.nBest wishes!n

With R19 it may be a look up table on a UDF. Have a look in the 2020 documentation as tables can be input into some fields. n

Thank you for your reply! nI didn't find the relevant information about a look up table in the Help documentation. Just the expression equations are used to describe the properties rather than a look up table in UDRGM.nCould you please tell me more details? Such as Chapter number, like 8.16.x (Real gas model) in user's guide or 8.2.6 (UDRGM) in customization manual.n

That suggests that the RGM are still function based. We're adding the ability to use tables in some parts of Fluent to simplify polynomial setup but it's an ongoing project. nAs I've not seen the paper (and won't download if you attach it: that's against the rules & copyright) I don't know what was done. n
