Development of a Method for Thermal Simulations Using USARIEM Avatars in COMSOL Multiphysics

Abstract

USARIEM has developed whole-body models, termed avatars, which are individualized 3D finite element (FE) models of Soldiers with complete internal anatomy. This report describes the methods used to convert a single avatar into a usable volumetric representation of a human that can be used for simulating responses to environmental factors. This current work specifically focuses on thermal simulations. Validation of this model was performed by comparing the simulation results to published data. The current validation is conducted in thermoneutral conditions with an ambient temperature of 27C. Data compared where the averages for the skin, fat, muscle, and esophagus. Errors for each of the measured tissues was less than 6.5% (skin, 3.31; fat, 6.32; muscle, 5.03; esophagus, 0.89). This work demonstrates the capability of this modeling approach, in conjunction with this type of anatomical data, can be used to produce an FE mesh avatar that is compatible with thermal simulations.
