D7.2 Finalization of "deterministic" verification and validation tests

Abstract

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
