When I tried to mesh the attached model I get the following error message 'Error 17860: The voxel grid generator has failed due to the maximum number of voxels being exceeded.'
I have an academic FEKO license. May I know the reason for this error message

If you want far fields, you could just request far fields (instead of near fields some distance away) and the number of voxels would be reduced by orders of magnitude.
But if you really want to use a near field definition, it would be much better using the default dielectric solver with the MoM (disable FDTD). Even with a 'Coarse' mesh setting your FDTD model will require more than 6e9 voxels.
The memory requirement and time to solve would be impractical.
