The Umbra simulation framework as applied to building HLA federates

Abstract

Sandia's Umbra modular simulation framework was designed to enable the modeling of robots for manufacturing, military, and security system concept evaluation. Umbra generalizes data-flow-based simulation to enable modeling of heterogeneous interaction phenomena via a multiple worlds abstraction. This and other features make Umbra particularly suitable for developing simulation federates. Umbra's HLA interface library utilizes DMSO's HLA Run Time Infrastructure 1.3-Next Generation (RTI 1.3-NG) software library to federate Umbra-based models into HLA environments. Examples draw on a first application that provides component technologies for the US Army JPSD's Joint Virtual Battlespace (JVB) simulation environment for Objective Force concept analysis.
