I keep getting this warning that linear tet mesh should be avoided to get correct results. Why is it so?nI tried hex mesh but I keep getting 'the mesh is intersecting' error and the mesher fails. Due to this error, I tried linear patch conforming tet mesh. If this doesn't get me correct results then what are the alternatives? nThank you. n

This 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. nnRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communitynn
