Mesh failed following video

florensix · March 21

I'm trying to run a lift coefficient analysis on an RQ Shadow model. I've been following a YouTube video, but I seen to be getting stuck on the meshing section. My model won't mesh and I have no idea how to fix it. if anyone can help it would be much appreciated. The main problem is my mesh fails.

I've provided my model and the YouTube video below.

The error could be due to geometry problem or due to wrong mesh sizing. Can you please check following?

Please check geometry in SpaceClaim. Select geometry in structure tree --> Use right click --> Select Check Geometry. The geometry should be error free to proceed. If geometry has any errors, please modify/recreate geometry at those places.
If geometry is error free, then please select 'CFD' as Physics Preference in meshing.
Please give body/face/edge sizing so that mesh has sufficient mesh density and resolve important features.
For the error, please use right click on the error and click on 'problematic geometry'. This will highlight geometry which is failing to mesh. You will need to modify geometry at this location or change mesh sizing.
If your meshing has special controls like periodicity, please check if those are correctly defined.

Please check following videos
