The information, commands, scripts, installation instructions, examples, and software-related material provided on this website are made available for informational, educational, and research-support purposes only. They are provided without any warranty, representation, guarantee, or promise of correctness, completeness, availability, security, compatibility, fitness for a particular purpose, reproducibility, or suitability for any specific technical, scientific, engineering, regulatory, commercial, or safety-critical application.
Any use of the provided material is entirely at the user’s own risk. Users are solely responsible for reviewing, understanding, testing, validating, and adapting all commands, scripts, software, model setups, numerical parameters, input data, output data, and simulation results before using them. Users are also solely responsible for maintaining backups, protecting their systems, checking downloaded files, complying with applicable licenses, and ensuring that their use of the material is lawful and technically appropriate.
Installer scripts may execute system-level commands, install or remove packages, modify user-level configuration files, create symbolic links, download third-party software, compile source code, and create desktop or menu entries. Such operations may fail, may be incompatible with a user’s system, may change the user’s computing environment, and may cause loss of time, loss of data, software conflicts, broken installations, or other technical problems. Users must inspect scripts before running them and must not run them on production systems, shared systems, institutional systems, or safety-critical systems unless they have the necessary authorization, expertise, backups, and recovery procedures.
Simulation tools, examples, scripts, and documentation do not constitute professional engineering advice, design verification, safety assessment, regulatory approval, or a substitute for independent expert judgment. Numerical models may contain errors, may be based on unsuitable assumptions, may be sensitive to input data, discretization, boundary conditions, solver settings, turbulence models, sediment-transport formulations, geometry processing, mesh generation, compiler behavior, platform differences, or third-party software changes. No guarantee is made that any simulation result is accurate, validated, reproducible, stable, conservative, or suitable for decision-making.
External links, package repositories, source-code repositories, documentation pages, third-party downloads, and third-party software are outside the control of the Author. Their availability, content, licenses, security, and behavior may change without notice. References to third-party or commercial products, projects, packages, repositories, or services do not imply endorsement, certification, warranty, support, or responsibility for those materials.
To the fullest extent permitted by applicable law, the Author, the Author’s employer, affiliated institutions, contributors, maintainers, funding bodies, sponsors, and any other parties involved in preparing or publishing the material disclaim all warranties and shall not be liable for any direct, indirect, incidental, special, consequential, exemplary, punitive, or other damages, including but not limited to loss of data, loss of revenue, loss of profit, interruption of work, system failure, software conflicts, incorrect calculations, incorrect simulation results, failed installations, engineering errors, regulatory consequences, or third-party claims arising from or related to access to, reliance on, execution of, modification of, or inability to use the material.
Nothing in this disclaimer excludes or limits liability where such exclusion or limitation is not permitted by applicable law, including liability for intentional misconduct, gross negligence, injury to life, body, or health, mandatory statutory liability, or any other liability that cannot legally be excluded or limited. If any part of this disclaimer is found to be invalid, unenforceable, or ineffective, the remaining parts remain unaffected to the greatest extent permitted by applicable law.
