In an injection file, the structure is:

(( x y z u v w diameter temperature mass-flow) name )

In a UDF, I know how to access most of these parameters:

 x: P_INIT_POS(p)[0]
 y: P_INIT_POS(p)[1]
 z: P_INIT_POS(p)[2]
 u: P_INIT_VEL(p)[0]
 v: P_INIT_VEL(p)[1]
 w: P_INIT_VEL(p)[2]
 diameter: P_INIT_DIAM(p)
 temperature: P_INIT_TEMP(p)
 mass-flow: P_FLOW_RATE(p)
 name: ?

Is is possible to use the name in a udf? For example: I want to print the name of a particle stream that reaches a certain surface, so I wrote the UDF:

DEFINE_DPM_BC(showname,p,t,f,f_normal,dim)
 {
 Message("%s\n",P_NAME(p));
 return PATH_ABORT;
 }

This does not work because P_NAME(p) is not the correct macro here, but what is?

(I also asked this question to Ansys support, if they give a working answer I will post it here.)

I received a quick answer from Ansys support: the "name" in each line of an injection file is optional, and is not used inside Fluent. Therefore it is not possible to use this name in a udf for Fluent.

Hello Pakk,
Hope you are fine,
I read your replying about Attaullah post on the mass transfer for absorption using the UDF.
I really need your help please,
I am trying to do the absorption process (acetone liquid absorbs acetone vapor) but I have no ideas how I do it.
Please, could you help me with the UDF and the set of the model?

I tried to send you a private message, but I couldn't.

Regards,
Hayder
