Problem with gravity related study

Hello everybody,

 

Currently i am having problems with the results of a study in solidworks which is using gravity.

The results are not as i would suspect.

 

The study i am trying to solve is from a air-duct installed on a deck of a ship.

The study is not included in the attached zip file.

 

The problem:

When i solve the study without the gravity (Only the reaction forces of the air duct on the middle bulb-profile) I get the result which is shown on the attached picture.

This is the result i would suspect. The deformation is symetrical and is the biggest in the middle.

 

When i include the gravity and resolve the study ( so the reaction forces of the air duct and the gravity are included) i get the results which are showing on the other picture.

This results are everything except symetrical.

 

I also attached the assembly.

Does anybody know a sollution or any explanation for these results?

 

Already a big thanks for helping!!
