Abstract

We demonstrate the feasibility of the domain decomposition method in simulating large scale finite element models through the ADVENTURE code, an open source freeware partly developed by the Computational Mechanics Laboratory at Kyushu University. Our model is that of hydrogen dispersion in a partially open space, chosen because of its relevance to the safe use of hydrogen as a potential replacement for fossil fuels. An analogy of the Boussinesq approximation is applied in our simulation. We describe the formulations and the model, followed by some results.
