Im trying to model geometry to simulate an antenna, but i find that the difference operation shows that the object is empty. Furthermore, when applying materials to the geometry, some of the shapes cant be selected despite what ive tried.
In comparison, when using an older version of COMSOL 5.3, this error doesnt seem to happen. Kidly let me know if there is anything i am missing, or is this a software issue.
I have added the file for reference.

Hello Anish,
5.4 is a rather old version and I do not have it installed on my machine. For what it's worth, I opened your file in the current version, 6.3, and I did not encounter any issue with the difference operation or material assignment.
Best,
Jeff
