I am simulating a structure which contains 28 micrometer thick silica substrate and on top of it i have 1nm thin grephene layer. grephene complex permittivity is given in the paper which depends on thickness of gephene layer. I am facing difficulty in meshing this structure. wavelengths are in THz region. How to mesh in this case.

You can upload your model here. There are experts in this forum, who can help you.

This model requires user defined meshing. You have 1 nm ultra-thin layer which requires highly dense mesh. I think this layer should have the maximum mesh size of [1/5] nm to correctly resolve.

But 1/5 nm messing taking lots of time ( in hours) . Is there any other way to implement it like transition boundary condition or something else.
