Fire Simulation and Residual Strength Prediction Tool for Aluminum Ship Structures During and After Fire: System Integration

In this proposal, we will develop and implement general thermal coupling schemes so that thermomechanical structural solvers, specialized fire-dynamics CFD codes and other thermal simulators may be employed in the solution of practical fire mechanics problems of interest to the Navy. This development will enable large-scale and physically accurate simulations of fire, structural degradation due to thermal effects, and fire evolution due to structural failure. The proposed Weidlinger Aluminum Structure Simulation Platform (WASSP) is conceived as an Application Programming Interface (API) which mediates the synchronized transfer of different classes of data between codes. The research that underlies this development is mainly concentrated to developing the appropriate coupling schemes that both respect the numerical performance and stability of the algorithms exchanging data and the realistic physics of the problem, including the orders of magnitude time-scale differences in the evolution of states in different domains.
