Undex Lung Computational Model

K&C proposes to develop a computational model of the human lung as it responds to underwater blast (UNDEX) insults. There are three core technologies that will be researched. The first core technology involves a detailed Finite Element (FE) model of the lung, including relevant tissues and organs in the torso, suitable for predicting the response of the lung to an underwater explosion event. The second core technology involves a robust and efficient methodology for UNDEX fluid-structure interaction (FSI) loads for application onto the lung/torso FE model. The final core technology is an end-user software product that automates the inputs to the computational model (e.g., UNDEX parameters, lung/torso parameters, and torso relative orientation to the explosive), running the coupled fluid and solid dynamics computations of the UNDEX-lung/torso interaction, post-processing the fluid and solid dynamic computational results, and interpreting and correlating the output to lung damage or injury thresholds.
