   Hi,

   My acoustic issue is non-linear, so I am wondering what are the non-linear terms simulated in K-Wave?

   According to the K-Wave user manual, it seems to solve the 1st order partial differential equation equivalent to the Westervelt equation? If not, how does it differ from the Westervelt equation?

   Hi KailingYI,

   The equations solved in k-Wave only differ from the Westervelt equation in the absorption term. The approximations made regarding the nonlinear term are equivalent ie, it accounts for the cumulative nonlinearity but not local nonlinearities.

   Hope that helps.

   Best wishes
   Ben
