Notus CFD is thoroughly verified and validated thanks to an important amount of numerical test cases and adequate processing tools. They are separated into two main topics, Verification and Validation:
When installing Notus CFD, the first step is to verify and validate that the version compiled on your hardware and sofware produce the expected results - see run notus guide. This script runs a collection of NTS files that cover most of the modeling and numerical methods of the code.
Most NTS files are sufficient to describe a case, but for some test cases, particular work is done in Fortran files compiled after the Notus library compilation. The directory src/notus/test_cases contains these Fortran files. Please refer to the developer's V&V page for more details.
