Mesh capturing

Hi all, long time user, new member;

I've been having some trouble running a simulation of a high lift rear wing I'm designing. Sometimes during the solving process (usually just after travel 3 has completed), Flow will try to capture the mesh but for some reason just hangs. The bar at the bottom of the screen will just run from 0-100 very rapidly and nothing happens. I've tried leaving it overnight to find it still there the next morning.

Quick look on here has given some things to try but nothing seems to work; cloning the project didnt work, restarting/clearing  solidworks data/previous results doesn't. I have run a simulation of a two element rear wing which was hit and miss (some would complete, some wouldnt). Just wondering if its something I'm doing...

I've attached the files if someone is wanting to give it a go themselves.

All help appreciated,

John
