SOLVCON is a software framework for solving hyperbolic partial differential equations (PDEs). SOLVCON uses the space-time Conservation Element and Solution Element (CESE) method for time-accurate solutions. The goal of SOLVCON is to enable high-fidelity solutions for design iterations. SOLVCON is...

Assimulo is a Cython/Python based simulation package for solving explicit ordinary differential equations (ODEs) and implicit ordinary differential equations (DAEs). The idea with Assimulo is to create a basis for simulating differential equations and to be easily extended with other solvers....

STIMATH is a high-level tool for mathematics, linear algebra, plotting and expression evaluation that can be used from any programming environment or even from a command line interface. It is an executable that takes a single argument, the name of a text file containing a series of MATLAB style...

Fortran Calculus Compiler: Calculus level computer languages are Fortran Calculus and PROSE. Both languages are based on what is called "Automatic Differentiation" (AD). Calculus languages simplify computer coding to an absolute minimum; i.e., a mathematical model, constraints, and the objective...
