Nice to meet you.

I am a university student using ANSYS for my research.

I would like to ask a question about an equation used in analysis.

If I want to substitute the pressure of a specific cell zone in the equation, it would look like this

pressure(["zone name"])

Now, if I want to use the pressure of a single computational grid instead of a cell zone, I would need to use a cell-level macro with UDF.

However, even after looking at the reference page, that programming is not clear to me. Can someone please advise me how to set this up?

I am looking forward to your answers.

There are a couple of approaches. Are the monitor points fixed or moving? If fixed it's a common work around to separate off a cell/facet to use in the UDF. Otherwise you're looking for a cell that contains a location rather than a cell by it's ID.
