Simulation of Fuel Tank Filling using a Multi-material Euler Solver with Multiple Adaptive Domains

The Adaptive Multiple Euler Domains technology in MSC.Dytran has been extended for the Multi-material Euler Solver. This paper demonstrates the application of this new method to the dynamics of fuel tank filling. The interest in applicability of MSC.Dytran to fuel tank filling originated from a major car manufacturer. The model includes both the fuel and the air inside the tank. The simulation process starts with properly initializing the fuel and air inside the tank under gravity loading. The fuel filling process will then be demonstrated, including the venting of air through a venting tube. The simulation is performed with MSC.Dytran.
