Development and applications of an embedded CSD approach for coupled CFDICSD modeling of blastlstructure interactions J.D. ~ a u m ' , E.L. ~estreau', H. ~ u o ' , R. ~ b h n e r ~ , D. pelessone3 & C. charman4 I Center for Applied Computational Sciences, ATG, SAIC, McLean, USA 2 CSI, George Mason University, Fairfax, USA 3 Engineering and Software System Solutions, Solana Beach, USA 4 General Atomics, San Diego, USA Abstract This paper describes recent developments and select applications of a program that couples parallel Computational Fluid Dynamics (CFD) and Computational Structural Dynamics (CSD) methodologies. FEFL098 is the CFD code used while DYNA3D handles the CSD portion. FEFL098 solves the time-dependent, compressible Euler and Reynolds-Averaged Navier-Stokes equations on an unstructured mesh of tetrahedral elements. DYNA3D solves explicitly the large deformation, large strain formulation equations on an unstructured grid composed of bricks and hexahedral elements. The initial algo
