Abstract: Real-time simulations of smoke propagation during fires in complex geometries are challenging. For the sake of computing time, accuracy could impact rescue decisions. We present a roadmap to build a real-time simulation and prognosis software for smoke propagation in underground stations. First, a fractional step method using finite differences is implemented. Second, we evaluate the Lattice-Boltzmann method due to its high parallelization capability and smart handling of complex boundaries and grids. By including live data through sensor coupling, accuracy is maintained and the prognosis is optimized by ensemble simulation. Further, acceleration is accomplished by dynamically extending the computational domain and multi-GPU support.
