   Hi

   I want to conduct a ultrasonic simulation of defects in metals by using k-wave.But I do not know how to define a defect, like a surface crack, in the MATLAB.I really wish you can help me.

   Thanks a lot
   sincerely

   Hi huxibunengshuo,

   In k-Wave, the medium properties (sound speed, density, etc) are defined as matrices, where each element of the matrix gives the medium property at the corresponding grid point. To simulate a defect, you will need to create a medium property map that has the properties of the defect (e.g., air or water) wherever the defect is present. Keep in mind that k-Wave uses a regular Cartesian grid, so this will restrict the crack geometries that you can represent. There is lots more information about k-Wave in the manual and the examples included in the toolbox if you need some specifics about how to define the matrices and run the model.

   Hope that helps,

   Brad.
