  Hello there,
  I am very excited to see the newest Lumerical FDTD support GPU computation, which really speeds up the simulation process. However, after running the simulation, there is nothing in the DFT monitor. I cannot visualize the E field or other results.
  Would someone help me with this issue?
  Thank you very much!

  We tested and everything looks normal.
  Please update to the latest version just released.
  If the problem still exists, please let us know your computer OS version.

  Hi, we figured it out finally. The name of the Lumerical file should not start with numbers. After I rename my file, I can see the saved results. I think this is a bug in the software backend.

  Thank you for this. Usually such file name should not be able to be saved.
