   Dear Bradley
   I can't understand the mathematical formula of calculating kgrid.Nt, i know it related to Nx and Ny but i don't understand how can we calculate it.
   Beside these parameters, is this related to PMLSize?
   Best regards
   Kian

   Hi Kian,

   Nt is the number of time steps. After you have chosen dt (see the k-Wave manual if you need further details), then Nt * dt will define how long the waves propagate for. For example, if you have a domain of a certain size and sound speed, you can set Nt such that the waves have time to propagate across the domain for example.

   Brad.
