Hi,

I have a question about the following cell macro: C_P(c,t). Does it give the static pressure? I don´t found any information about this in the FLUENT Manual.

Moreoever, the unit is the Pascal, or?

I wrote the following UDF, but I have seen UDF where the term "C_UDMI(c, t, 0) was used to store the cell value. Is it mandatory to use it?

Regards,

Maxime

It does give the static pressure. All variables in Fluent UDF are SI. So for pressure it is in Pa. Regarding UDMI it is just for debugging here not really required.

I recommend attending a UDF training Maxime .

Hello Dr. Amine,

How can one attend a training on UDFs and expressions in Ansys Fluent? Are there any upcoming trainings?

There are training materials on the Ansys Learning Hub, which requires a subscription.  https://www.ansys.com/training-center/course-catalog/training-for-you   That course should be pre-recorded so can be done at your convenience. 

We also offer bespoke training, but I'd always take the standard course first. Note, the training is only intended to provide the knowledge to write the code, you'd still need to do all of the coding yourself.
