NimbleSM is a Lagrangian finite-element code for solid mechanics. Its primary application is the solution of mechanics problems on nonuniform, three-dimensional meshes using either explicit transient dynamic or implicit quasi-static time integration. Additional features include multiscale modeling and the simulation of contact. The NimbleSM code base is designed for performance portability across varying hardware architectures.

NimbleSM may be built with the following optional dependencies:

Library for I/O. It is highly recommended that you build NimbleSM with exodus support. The alternative is an exceedingly slow text-based I/O system.
