  HI Commenty; I try to sumilate some EM wave by using FDTD and I am wondering which Mesh settings I have to use to get a good simulation, because there are many mesh type (auto non-uniform with mesh accuracy until 8, uniform and custom non-uniform) could you some one explain for me what is the different between them and how can I choose the best mesh type for my , thank you

  Hi Soufiane,
  Thank you for reaching out to us! Your question is very interesting, I believe you can find a lot of guidance going through these two articles: Selecting the best mesh refinement option in the FDTD simulation object and Understanding Mesh Refinement and Conformal Mesh in FDTD. Also note that it is normal not to know the exact mesh settings for your simulation on your first try. It can end up on a trade between time memory and accuracy. For that reason we recommend to do a Convergence testing process for FDTD simulations.
  Kind Regards,
  Niki
