This deliverable focus on the verification and validation of the solvers of Kratos Multiphysics which are used within ExaQUte. These solvers comprise standard body-fitted approaches and novel embedded approaches for the Computational Fluid Dynamics (CFD) simulations carried out within ExaQUte. Firstly, the standard body-fitted CFD solver is validated on a benchmark problem of high rise building - CAARC benchmark and subsequently the novel embedded CFD solver is verified against the solution of the body-fitted solver. Especially for the novel embedded approach, a workflow is presented on which the exact parameterized Computer-Aided Design (CAD) model is used in an efficient manner for the underlying CFD simulations.
It includes:

  • A note on the space-time methods
  • Verification results for the body-fitted solver based on the CAARC benchmark
  • Workflow consisting of importing an exact CAD model, tessellating it and performing embedded CFD on it
  • Verification results for the embedded solver based on a high-rise building
  • API definition and usage
