Meshing Error

For the glass substrate model geometry (attached below), I am trying to create a mesh. However, I am encountering this error:
""The current physics settings induce a mesh requirement of about 1.1e+07 elements.
Trying to fulfill this requirement may cause out of memory errors or process locking. Switching to user-controlled mesh.
Please review mesh settings carefully before building the user-controlled mesh, or switch back to physics-controlled mesh and change physics settings.""
Please help me on how I can rectify my physics settings. In my mind, my model is not that complicated, indeed, it's just a slab of Silica glass so I don't understand why the number of elements is that many.

For plate-like structures, often a swept mesh is a good idea.

Is the .mph attached now? I am really sorry for this delay. I am new to this.

I don't have the ewfd module, but I can see why you get that error if the software tries to generate a physics-controlled mesh. You are trying to model infrared light (1 micron wavelength) in a computational volume that is a one meter in radius and 5 mm thick. You either need to: (1) model something with a much smaller volume or (2) change your computational method to something that doesn't require resolution on the wavelength scale. Good luck.

Hello Dr. Koslover. Your advice, specifically (2), worked. Thank you very much.
