JRJ Simulation & Design provides consulting services in several areas to Silicon Valley technology companies. JRJ utilizes a variety of tools to solve 2D/3D acoustic, ultrasonic, and electro-mechanical design and design optimization problems. These tools include industry-standard design and simulation packages (e.g., PZFlex™, ANSYS/Multi-Physics™, ZEMAX®, AutoCAD®, MATLAB®) as well as custom wave propagation codes developed for optical and acoustic modeling applications. Some simple computational modeling examples are provided here. Brief descriptions and PDF files of bioacoustic modeling research can be viewed here.
