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. nI've provided my model and the YouTube video below.n(3) UAV CFD SIMULATION WITH FLUENT (PART 1/4) - YouTubenhttps://drive.google.com/file/d/1hQYVyKNoDNj61nD2j0zHIBQLHMVYVh1m/view?usp=sharingn

As ANSYS Staff, we can not download attachments. Please upload images using upload image functionality. nThe error could be due to geometry problem or due to wrong mesh sizing. Can you please check following? nPlease 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.nIf geometry is error free, then please select 'CFD' as Physics Preference in meshing. nPlease give body/face/edge sizing so that mesh has sufficient mesh density and resolve important features. nFor 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. nIf your meshing has special controls like periodicity, please check if those are correctly defined. nPlease check following videosnnAnsys Meshing

No geometry errors.nThe problem seems to the airfoils.n

Looks like it has single surface. Please split that surface in more than 3-4 faces. Then use some local sizing as well. nPlease check following videosnnAnsys Meshing
