• 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.
