The tests directory in the repository has hundreds of
grep-able examples- unit and regression tests,
- (crude) mathematical & code verification tests (as in "are we solving right the equations?"),
- subdirectories with further case studies
- Both free as in "free speech" and in "free beer"
- The problem to solve is defined through a syntactically-sugared self-descriptive English-like plain-text input file that should resemble the original human-friendly problem formulation as much as possible:
- no need to recompile if the problem changes (FeenoX is a program, not a library)
- nouns are definitions and verbs are instructions
- simple problems need simple inputs
- everything is an expression
- 100%-defined user output (no
PRINTnorWRITE_RESULTSinstructions, no output)
- Cloud-first design (cloud friendliness is not enough)
- MPI parallelization
- Leverages high-quality well-established free and open source libraries to solve...
- general mathematical problems using GNU GSL
- sets of ODEs/DAEs using SUNDIALS
- PDEs formulated with the finite element method
- Focuses on flexibility, especially when defining non-uniform multi-solid material properties from ASME tables
- Follows the Unix programming philosophy
- Each PDE (i.e. from Laplace downward in the list of examples) is implemented in a subdirectory within
src/pdeof the source tree- any subdirectory can be removed if a particular PDE is not needed
- any subdirectory can be used as a template to add a new PDE to the capabilities
- Space, time and/or solution-dependent material properties and boundary conditions
- Command-line argument expansion for
- Steady-state, [quasi-static] and/or transient problems
- Linear and non-linear problems
- Possibility to verify the code using the Method of Manufactured Solutions
- Separate repository to profile and study code performance using Google's benchmark library
