The Umbra simulation framework as applied to building HLA federates
Eric J. Gottlieb, Michael J. McDonald, Fred Oppel, James Brian Rigdon, Patrick G. Xavier · 2003
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.
