How to get a cell pressure and temperature in fluent expressions?

[SRP]

Hi,

You can get the values of pressure and temperature as Expressions > Variables. You can see in the variable pressure and temeperature is mentioned.

You can check fluent user's guide for more details: 5.3. Creating and Using Expressions (ansys.com)

Thank you.

Thank you. Can we get the time derivatives of a variable in expressions? Like I have  a scalar and I need its time derivative in the expressions.

Hi,

Normally derivatives are not available in Fluent. you can always use UDF and save it in UDM and use it when required.

Thank you.
