Can anyone help me to translate a 3D solid fluent model to Abaqus solid mesh When I am using the builtin translator in Fluent to do the same the tetra is being translated in Abaqus as a triangular element. All help is greatly appreciated !!!

Export it from Tgrid and not from Fluent.

Thanks Joern.... tgrid doesn't Export abaqus format. ICEMCFD cannot read in the NASTRAN file from Tgrid properly and also cannot read in Fluent file

What cell types do you use? Are there any pyramids? The nastran format can not deal with these elements. Otherwise you should be able to use nastran or patran format to exchange meshes.
