The Multidisciplinary-design Adaptation and Sensitivity Toolkit (MAST) is a sensitivity-enabled, multiphysics FEA tool developed to support computational design and engineering analysis.

In addition to analysis of complex, nonlinear physics on large built-up models, MAST supports efficient analytical gradient/sensitivity calculation using direct and adjoint methods. As a result, it is well suited for gradient-based multidisciplinary design optimization processes.

MAST is developed at the Computational Dynamics and Design Laboratory at Mississippi State University in collaboration with the Air Force Research Laboratory (AFRL) Multidisciplinary Science and Technology Center (MSTC).

The MAST website is https://mastmultiphysics.github.io and includes examples/tutorials, API documentation, and a growing theory/users guide.
