  Hello,
  In FDTD, all simulations stop from the step of initialization and do not go to the analysis mode, although they were working very well before. Do you know what could be the reason for that?
  Thanks

  It worked when I uninstalled Matlab from the computer. Is there any explanation for that? especially that I need to transfer the data to Matlab.

  What is the OS of your machine? Which version of Lumerical and Matlab are you using? If you need to run Matlab on the same computer, and not using the Lumerical Matlab integration, disable the Matlab integration in the Lumerical CAD. Otherwise, set the Lumerical Matlab integration with a supported version of Matlab. You may have to add the Matlab and Lumerical API PATH into your system.
