ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid
- Write equations in a text file and solve them for any unknown variable
- Build up large hierarchical models containing trees of sub-models
- Solve non-linear systems of equations, as well as dynamic systems
- Enter your units of measurement directly, ASCEND does the conversions
- Reuse external code (C, C++, Fortran) in your models
Found it very useful and very helpful.
