abstract

In this technical effort we have incorporated the Detonation Shock Dynamics (DSD) methodology into the Eulerian hydrocode CTH by coupling it to a DSD code called WAVETRACKER. Based on some preliminary work, we developed a strategy for coupling these two codes. Both CTH and WAVETRACKER are stand-alone codes. In the coupled code, CTH calls WAVETRACKER as a subroutine. Interface routines are developed to pass geometry, mesh and boundary information from CTH to WAVETRACKER. Additional parameters required by WAVETRACKER are read directly from a user input file. Results in the form of a burn table are interpolated and passed back from WAVETRACKER to CTH.
