Hello all,

I'm running a transient simulation in Fluent and I want to define a non-constant fluid inlet temperature.

My inlet temperature depends on the temperature of a cell zone and I know what the inlet temperature should be at different temperatures of that cell zone. I need Fluent to interpolate the inlet temperature between the ranges and not change abruptly (which I could even do manually).

For example,

At 650°C of cell zone, inlet temperature = 100°C,
At 600°C of cell zone, inlet temperature = 80°C,
At 500!C of cell zone, inlet temperature = 55°C,

...and so on.

Thank you!

Hi,

I recommend creating a UDF for inlet temperature.

For more details, please refer to fluent customization manual: 1.3. Defining Your UDF Using DEFINE Macros (ansys.com)

Thank you
