The Department of Energy National Nuclear Security Administration awarded a $1.711 million Cooperative Agreement to Brown University on September 22, 2025, under the Predictive Science Academic Alliance Program (CFDA 81.124) to develop robust, high-order-accurate, mesh-independent numerical methods for inequality-constrained problems in computational mechanics. The Center for Information Geometric Mechanics and Optimization (CIGMO) will develop algorithms and their efficient implementations to simulate and optimize inequality-constrained physical systems.

Work is performed in Providence, Rhode Island, with a period of performance through September 21, 2030. The program supports advanced computational science investigations aligned with NNSA's verification, validation, and uncertainty quantification methodologies for large-scale simulations.

Brown University is distributing sub-awards to two collaborating research universities. New York University received a sub-award on December 18, 2025, to conduct collaborative research on numerical methods for constrained computational mechanics and optimization using information geometric techniques. Georgia Tech Research Corporation received a sub-award on March 30, 2026, for the same focus area of developing numerical methods for constrained computational mechanics and optimization leveraging information geometry.

The center for information geometric mechanics and optimization (CIGMO) will develop robust, high order-accurate, mesh-independent numerical methods for inequality-constrained problems in computational mechanics. Overall goal: develop robust, high-order, mesh-independent algorithms and their efficient implementations to simulate and optimize inequality-constrained physical systems.
