FEM simulation error

I imported a simple waveguide transition as a .step file. Running an FEM simulation was successful. I attempted to import a copy of this part and join the two pieces back to back (in order to simulate "calibrating" adapters). I joined them together and upon trying to run the FEM simulation, received this:

                    |              MESHING                |                           SOLVING
level   freq(GHz)  |  nbTetr  Elapsed time    CPU time   |  nbUnknowns   mem(GB)   Elapsed time    CPU time           Delta(S)  solver  nbIter     normRes
agilentfem failed to complete successfully: No currents were found  on Port 1.
!!! ERROR !!!!!!!!!!!!!!!!!!!!!!!
ABORT: non-zero return value <1> of the following command

Any thoughts?
