Help in modifing geometry for sweep mesh

[adib.aktab999]

I have created geometry in solidworks.

 

I have extracted the fluid region for fluent simulation,

I am trying to do hex mesh or sweep mesh, how can I modify my geometry in space claim so that my fluid body becomes sweepable??

You can suggest me yt videos or ansys courses where i can understand the theory of sweep mesh and share topology options on space claim.
