Transmit Model Execution 

Model Description 

Pulse Echo techniques are commonly used for NDT applications for quality control or to characterize the internal structures of objects. This example is a 2D model and simulates a PZT plate with backing sending a signal into water load where it bounces off a rigid reflector and is received.
