  Array, Were you able to run this simulation before? Is this happening to all FDTD simulations? Check the simulation's memory requirements. Try to run the example simulation 'mwp.fsp' from the Applications Gallery (Apps).

  Lito How do I check the simulations memory requirement?

  I also meet this question when I changed the wavelength only.
  When I used the wavelength of 1550nm， it can run normally.
  But when I changed to 532 nm, it shows this error.
  
  So, could you give me a hand?what should I do ?

  HLL,
  Does the error happen to all simulation files including the examples from the Application Gallery (Apps)?

  Dear Sir,
  
  Other simulation files can run normally, just it happened when I changed the wavelength from 1550nm to 532nm.
  But when I changed the wavelength from 1550 to 1500, it also works.

  Dear Sir,
  
  Luckily, I find the reason for this error is when we changed the wavelength, the memory of files increased greatly. So the computer could not run it anymore.
  
  When I changed to the supercomputer, it will run.

  When I use wavelength of 1500 micrometer the 3D simulation works perfectly but when I use 1.5 micrometer wavelength 3D simulation does not work.
  Why??can somone help?
