Title:Verification and Validation of an Overset Fluid-Structure Interaction Solver (3:30PM-4:30PM)
Seminar:CCMA PDEs and Numerical Methods Seminar Series
Speaker:Cooper Elsworth, Penn State Univeristy
Abstract:
Existing overset mesh technology has been incorporated into an ALE based Fluid-Structure Interaction (FSI) code, producing a novel approach for investigating fully-coupled FSI phenomena. In particular, the Suggar++/DiRTlib overset mesh technology has been implemented into a partitioned FSI solver based on OpenFOAM and in-house structural codes. The impetus of this solver has been to address some of the problems that occur in complex FSI simulations, most notably concerns with the mesh motion experienced in large deformation cases. The solver intends to simplify mesh generation, maintain mesh quality throughout the simulation, and provide similar performance to current approaches through the implementation of overset methods. This talk presents the effects of overset methods on FSI simulations, as well as provides validation for the overset FSI solver. Use of the Turek and Hron benchmark case has allowed for the use of a consistent case in the comparison of the proposed solver to current FSI method results and performance. Simulation data will be presented, while investigations into the benefits of overset methods for FSI simulations will be discussed. In addition, the relative performance of the solver has been presented, in order to address the viability of the proposed solver's application. The talk is 3:30PM-4:30PM
