Automated Fluid-Structure Interaction Analysis
Abstract
An automated Fluid-Structure Interaction (FSI) analysis procedure has been developed at ATK Thiokol Propulsion that couples computational fluid dynamics (CFD) and structural finite element (FE) analysis to solve FSI problems. The procedure externally couples a steady-state CFD analysis using Fluent and a structural FE analysis using ABAQUS. Pressure results from the CFD solution are interpolated and applied as pressure boundary conditions on the structural model. Displacements from the structural analysis are interpolated and applied to the boundary of the CFD mesh. Iteration between the CFD and the structural analysis continues until a solution is reached. The FSI procedure provides controls to monitor the solution and define termination criteria, as well as manage output. Automatic report generation of the solution is another feature of the FSI procedure. Plans and funding are in place to extend the FSI procedure to include coupling with thermal analysis as well.
