Aneurysm case with different STL file

Hello everyone
I am trying to use aneurysm case with a different .STL file. (simple a pipe ) . I have created stl file of the pipe . I am not a pro-programmer so I ran into some issues that i can’t understand. I am pretty sure their solution are simple.

Reynolds number, based on provided inlet diameter: 117.499

Running new simulation at level 0

Segmentation fault

this is the Error in Terminal . I would appreciate the help and thank you in advance. 
I don't need any specific answer. For example if you could tell me where i should look for the problem or if my stl file has some problems. I will look into that. I just want pointers so I could find the problem. any suggestion where the problem might be is ok as well .

I was able to solve the problem using another stl file. segmentation error is due to bad stl files
