Abstract:
Molecular-continuum flow simulations concurrently couple (an ensemble of) molecular dynamics (MD) simulations with computational fluid dynamics (CFD) solvers in a domain decomposition sense.
Our main objective is to pave the way towards error-controlled molecular-continuum flow simulations on supercomputers in terms of both statistical errors and hardware faults. In the short term, project results shall flow into other research activities on multiscale flow simulations with the macro-micro-coupling tool (MaMiCo) [1], amongst others into a soon-to-start project on molecular-continuum simulation of multi-phase/multi-component systems. In the long term, work on noise reduction and fault tolerance shall feed into a to-be-established research strand on integrating data science and HPC at HSU. Data science is the key challenge nowadays, and HSU is pursuing research in this field across basically all faculties.
