DGTD having STL files does not work

One of our customers has been looking into electric field at a small gap by using DGTD (2021R2). He pointed out that DGTD does not work when a STL file is inserted. He asked me to investigate the reason.

I downloaded a STL file that fabricates a sphere from the following site. https://commons.wikimedia.org/wiki/File:Sphere.stl

When the STL file was inserted into FDTD, the simulation was properly run, as described in the attached file. However, when it was inserted into DGTD, it was not possible to even apply the simulation mesh. I changed some parameters, though, I was not able to solve that.

Would someone have any idea to solve this issue?
