  Hi, when I use my own material data with proper definition in material database it happens that when I launch a simulation braodband in varFDTD 2.5 it gives me divergence... so that I can't simulate the behaviour of the dispersion on my field.
  It works properly the narrowband option with same conditions..I tried to change all the parameters about mesh/boundaries/ fitting but nothing.
  Any suggestions?
  Thanks

  Hi,
  Can you share the screenshot of the error message ?
  You can also get in depth information about diverging simulation in the following link:

  Thanks and regards
