I use prepomax version 2.2.0.  
When importing an INP file, I have a very large number of parts (user message: only the first 9K are imported).

I have only one single ELSET (S3 type) in the file, but it looks like one elset was created by TRIA3 element !

Yes, this is a hard-coded limit. Unfortunately, more parts in one model are not supported. Why do you need so many parts?

Matej  
I don’t need so many parts. I just want to understand Why I get All those parts and then what s wrong with my INP file (or what is missing).  
Thanks

You need to provide your inp file for others to check. Shouldn’t creat part for each element.
