Tecplot is able to load both Flow 3D and Abaqus data. The issue is that before you can interpolate, you will need to make sure that the grids align for both meshes.
Once loaded into Tecplot and aligned appropriately you can use the tool under Data > Interpolate to transfer Temperature from the FE Tet to the cylindrical. The following is from our user's manual:
In Tecplot 360, you can interpolate the irregular I-ordered data onto an IJ-ordered mesh, and then create
contour plots and other types of field plots with the interpolated data. You can also interpolate your 3D, Iordered
irregular data into an IJK-ordered zone and create 3D volume plots from the IJK-ordered zone.
You can even interpolate to a finite element zone.
The accuracy of the interpolation will depend on your data, the density of the destination grid, how well
the grid fits the area of your unorganized zone and the settings used for interpolation.
It is Chapter 21 - 11, page 331. It also explains the three methods of Interpolation available.
