For CAViDS Consortium Internal Use Only 3 Hydraulic Line FSI For CAViDS Consortium Internal Use Only CAViDS Consortium Project Progress ABAQUS FSI ABAQUS/CFD + ABAQUS Standard • The hydraulic line problem as specified involves strong physics coupling between the fluid dynamics and the structural dynamics. • The strong coupling requires much closely coupled interactions between CFD and CSM solvers than what is used in the current coupling scheme (sequential explicit coupling). • The sequential explicit coupling method is considered a “loose” or “weak” coupling scheme, which is best suited for FSI analysis with a weak physics coupling. • It is not recommended to use Abaqus/CFD + Abaqus/Standard for the specified conditions of the hydraulic line FSI analysis. • Further approaches to consider are FSI implementation in – – – Abaqus/CFD+Abauqs/Explicit. ANSYS Workbench, as it provides the iterative or “strong” coupling scheme. Next release of MpCCI, that couples Abaqus/Standard with ANSYS FLUENT iteratively. Computational Engineering Physics Lab.
