Export to FLUENT

I am trying to export a 3-D Mesh with FLUENT 5/6 as solver and i am getting the messasge : "Face # has higher order elements and cannot be exported to fluent 5 format."

I am using tri elements and the Grid design is a conical pipe. I experimented with other kinds of elements but errors having to do with how the elements fit to the surface appear.

Can it be that the FLUENT 5/6 is not able to solve 3-D mesh elements?

Is it complaining about 3D elements or quadratic (2nd order) elements?

Probably the later. Fluent is a "linear" element solver, so you must make sure that you are dealing with tetra-4 and tri-3 type elements, not tetra-12 or tri-6.

Other solvers (usually FEA solvers such as ANSYS Mechanical) prefer 2nd order elements for increased accuracy, but can usually work with both.
