Hi to all.
I am trying to prepare .stl file for cfd simulation. I downloaded stl file and I am trying to make a solid from it so I can model it further because I am a newbie in Solidworks surface. If someone would make a solid from my file I would appreciate it a lot. I still get two open surfaces which I can not correct.
Thank you in advance.

PS:

In .rar file I added original .stl file
