Request for Assistance with Feko Simulation Errors: ERROR 33052 & ERROR 39518

I am encountering issues while running simulations for dipole antennas at 100 MHz using Feko, and I would appreciate your assistance in resolving them.

1. Basic Cylinder Dipole Antenna
The 100 MHz calculation for this antenna is performed using MLFMM (Multilevel Fast Multipole Method) to reduce computation time. However, the following error is displayed:

ERROR 33052: Internal Feko error.
This error prevents the simulation from completing, and I have checked the output file cylinder_dipole_100MHz.out for additional details, but I have been unable to identify the cause.
2. Full-Sheath Dipole Antenna
For the full-sheath dipole antenna, I receive the following error:

ERROR 39518: An edge port may not be defined on the surface of a dielectric body.
I tried setting the surface of the edge port as PEC (Perfect Electric Conductor) on the dielectric boundary, but this did not resolve the issue. I would appreciate any guidance on how to proceed.
Could you please provide insights or recommendations to address these issues? The relevant output files are available if needed.

Best regards,
NoYa
