   Hi

   I encountered a problem recently.
   When my medium.sound_speed is set too large,error message will appear.
   How do I know the maximum value of the medium.sound_speed to avoid exceeding?

   Thanks!

   Hi Moonssa,

   My guess is the simulation has become unstable. Try reducing the size of the time step (or CFL). You can check the time step using the function checkStability. Let me know if that doesn't solve it.
