Title: Meshing Problem
Post by: anger_666 on July 05, 2021, 06:15:56 am

Hello Guys,

I want to ask a questions for you about PyroSim. After finish my car-lot design, meshing seems ok. But after starting analysis the error is occurred. For ex: "Vent 25 must be attached to a solid obsturction."
The problem is how can I find the Vent 25. Because I changed the name. After changing the name there is no vent25 in my project.
Thanks.

In such a situation, I simply counted all the valves one by one - in the project tree - and then I tracked which valve was the problem

It should be the 25th Vent down from the top of the FDS input file.
