Application of the HERA-C Eulerian Code to Selected Conventional Defense Configurations

HERA-C is a multi-material, large-deformation, strong shock wave, solid mechanics code developed at CEA.

The Eulerian code HERA-C relies on advanced numerical methods (BBC, GAD, GAIA), adaptive mesh refinement, and high-performance computing to deliver both accurate and efficient results.

These capabilities are applied in conventional defense, particularly in high-explosive reactive burn models, to simulate explosion and blast wave effects, ballistic impacts on metals and concrete, and the behavior of shaped charge jets.

Here, we focus on a selection of simulations that highlight HERA-C's capabilities in assessing these areas.
