from where you are exporting mesh? is it workbench meshing?
make sure you have volume mesh generated. then use file -> export. please use fluent option to export mesh.
if it gives error of overlapping named selection, use right click on named selection and use fix overlapping named selection. then again export the mesh.
If this helps, please mark this post as 'Is Solution' to help others.
