The facts
Each one read from turtleFSI's own pages, with the date it was checked.
What it does
- Assessment tools
- Nochecked 23 Sep 2026
- Checkpointing
- Built-in functionality supports saving checkpoints at a chosen frequency and restarting from a previous checkpoint.checked 5 Oct 2026
- Command line
- Parameters can be controlled from the command line, and a specific problem file can be run with `turtleFSI --problem [path_to_problem]`.checked 12 Oct 2026
- Custom problems
- Users define problem files with functions for parameters, mesh and boundary markers, boundary conditions, and optional simulation hooks.checked 12 Oct 2026
- Dependencies
- The documentation lists FEniCS 2019.1.0, NumPy, and Python 3.7 or later as dependencies.checked 12 Oct 2026
- Distribution
- The development version is available from the project’s GitHub repository and can be installed from source with `python setup.py install`.checked 12 Oct 2026
- Features
- The solver includes checkpointing and restart support, plus saving files for visualization.checked 12 Oct 2026
- Installation
- The project recommends Anaconda or Miniconda installation on macOS or Linux and building from source on HPC clusters.checked 12 Oct 2026
- Integrations
- The documentation describes using ParaView to view simulation output and points users to FEniCS resources for meshing questions.checked 12 Oct 2026
- Known issue
- The documentation lists an issue page that includes a MUMPS failure error message topic.checked 12 Oct 2026
- Known limitation
- For large problems, often 3D problems with many degrees of freedom and several tens of processors, the default MUMPS solver may fail, possibly because it lacks memory for the linear system.checked 5 Oct 2026
- Lesson library
- Nochecked 23 Sep 2026
- License
- The repository states that turtleFSI is licensed under GNU GPL version 3 or any later version.checked 12 Oct 2026
- Mesh lifting
- It provides mesh lifting options including Laplace and biharmonic methods, with biharmonic described as more robust for large deformations but more computationally expensive and memory intensive.checked 5 Oct 2026
- Parallel computing
- The solver can run with MPI parallel tasks using FEniCS HPC functionality.checked 12 Oct 2026
- Purpose
- turtleFSI is a monolithic fluid-structure interaction solver written in FEniCS for researchers and others investigating fluid-structure interaction problems.checked 12 Oct 2026
- Security
- The project pages reviewed do not state security certifications or compliance claims.checked 12 Oct 2026
- Simulation controls
- Users can set simulation parameters from the command line and supply their own problem file.checked 5 Oct 2026
- Support
- The repository directs users to its GitHub issue tracker to report bugs and other issues.checked 12 Oct 2026
- Visualization
- Simulation output can include XDMF files for visualization in tools such as ParaView.checked 12 Oct 2026
Where it runs
- Solver approach
- The project describes turtleFSI as a fully monolithic solver using the classical arbitrary Lagrangian-Eulerian formulation.checked 5 Oct 2026
