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.</p> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/simulation-of-defects-in-metals#post-5464 Thu, 14 Apr 2016 03:38:37 +0000 huxibunengshuo 5464@http://www.k-wave.org/forum/ <p>Hi</p> <p>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.</p> <p>Thanks a lot<br /> sincerely </p>
