For instance if I choose kgrid.dt = 4ns, does it mean that sample frequency for the toneburst should be f_sample = 1/4ns? Or I can choose these values independently? Nevertheless, by running a simulation (Pulse echo) if I fix dt = 8ns and f_sample = 1/8ns I have stability issues, but this can be easily solved by choosing f_sample independently from dt. Is it possible to have few comments on that?</p> <p>Best </p>
