Enabling high-resolution, data-driven conflict simulation for US military, domestic, and international partners
Since 1974, the Conflict Simulation Laboratory (CSL) has provided state-of-the-art simulation and modeling tools, including the Joint Conflict and Tactical Simulation (JCATS) and the JCATS Low Overhead Driver (JLOD).
JCATS is a discrete event, constructive simulation that simulates effects-based, entity-level conflict scenarios. JCATS may be used stand alone or in federations using High Level Architecture (HLA) or Distributed Interactive Simulation (DIS) bridges.How to get JCATS
JLOD is a multi-sided, white cell simulation tool that models force interactions on a global-level down to the individual entity. Together, JCATS and JLOD enable world-wide conflict simulation with high-fidelity simulation in targeted areas.How to get JLOD
Due to the continued coronavirus pandemic, the 14th Annual JCATS International Users Conference is cancelled for this calendar year. We continue to monitor the coronavirus situation and are looking at other options for hosting an event to bring the JCATS users community together to share your ideas and enhancement requests.
Please continue to check the JCATS webpage for updates and remember that you can always send your requests for enhancements or improvements to the JCATS software to us at support [at] odo.llnl.gov.
We hope that all of you are staying safe and healthy. We look forward to hearing from you and wish you all well through these difficult times.
JCATS and JLOD have transitioned to the RHEL V7 Operating System. RHEL V6 Operating System is no longer supported. JCATS V16.0 and JLOD V8.0 will only be supported on RHEL V7.7 and RHEL V7.8 (if it is released before JCATS/JLOD). RHEL V7.6 will not be supported.
