Hello everyone,

I'm a new one in this forum.

My question is quite simple. I want to write the cell information of the solid domain to the txt file by UDF.
I just want this code to be executed only one time because I just want to know the exact position (x,y,z coordinates) and the cell index for the solid part mesh.
I have no idea which kind of UDF should I used.

Any information could be helpful to me.

Thanks a lot.
Hope you guys have a nice day.

Shen
