The reason for attaching a comprehensive collection of test problems is to offer the possibility of trying out different discretization procedures, differential equation solvers, and data fitting algorithms. The problems can be used for selecting a reference problem when implementing one's own dynamical models, or to test the accuracy and efficiency of numerical algorithms. All problems are executable, and a powerful filter allows you to search for those related to your own application.
The problems are implemented in the
PCOMP
language. Fortran code for function and gradient
calculation can be generated by an auxiliary code that is attached. To summarize, we offer test problems for the following model classes:
| explicit model functions: | 243 |
| Laplace transforms: | 10 |
| steady state equations: | 41 |
| ordinary differential equations: | 575 |
| differential algebraic equations: | 62 |
| partial differential equations: | 325 |
| partial differential algebraic equations: | 44 |
| sum: | 1,300 |
The test cases are also distributed independently of EASY-FITModelDesign, see download page.
