Hello everyone！

I read a data table of saturated pressure and saturated temperature in Fluent. This table determines the corresponding temperature or pressure for a saturated state using linear interpolation. However, how can I obtain a pointer to this table in a User-Defined Function (UDF)?

In the UDF documentation, I came across a macro that returns the corresponding saturated pressure in the table based on temperature:
`Get_Tabular_P_Given_T(tabular_data, T)`

However, this macro requires a pointer to the data table `tabular_data` as an input. How can I obtain this pointer within the UDF?

Alternatively, are there other methods, such as directly defining this data table within the UDF? If so, how would I go about doing that?

Thanks
