%0Computer Program %TTempus v. 1.0 %XTempus is a software framework for the time integration of ordinary differential equations (ODEs), partial differential equations (PDEs), and differential-algebraic equations (DAEs). Examples of time-integration methods available are Forward Euler, Backward Euler, Explicit Runge-Kutta and Implicit Runge-Kutta methods. Tempus can be used from small systems of equations (e.g., single ODEs for the time evolution of plasticity models) to large-scale transient simulations requiring exascale computing (e.g., flow fields around reentry vehicles and magneto-hydrodynamics). Tempus will be released as part of Trilinos under a BSD open source license. %AObert, Curtis %APawlowski, Roger %ACyr, Eric %AConde, Sidafa %Rhttps://doi.org/10.11578/dc.20201001.20 %Uhttps://www.osti.gov/doecode/biblio/45306 %CUnited States %D2017 %GEnglish %2USDOE %1AC04-94AL85000 2017-02-09
