hello everyone.
my ultimate goal is to simulate a simplified version of a water/air eductor in order to collect the bubble dimensions from the outlet to the top of the water tank (including coalesce of one bubble to another).

Using SolidWorks I created the model and I am using the fill command to create the geometry for Fluid. Although when I am trying to create the fluid path inside the pipe, "cannot heal wound" comes up.

Second, at the top, the water is supposed to be stopped by a blind flange and escape from the open gap all around the top. although I cannot fill that space fully either.

I would greatly appreciate if you give me some help on these issues.
Do not hesitate to ask me anything else that I might have missed on the description above
Thanks!

EDIT:
Reading through the sticky, it is mentioned to add the model files if possible. Link to the zip file:

EDIT 21/04:
I have been playing around with other ways of filling up the area in question, with no luck. I would greatly appreciate any help, please
