Closely coupled dynamic interaction between fluid and structural domains (DFSI) is a significant computational challenge.
This chapter describes an approach to the parallelisation of DFSI that employs:
DFSI presents one such class of closely coupled multi-physics problems which is very compute intensive. In this contribution a parallelisation strategy which capitalises on group solver technology, which enables only the physics active in a specific sub-domain to be solved, and a multi-phase partitioning strategy, using the mesh partitioner JOSTLE, which enables a very even load balance to be achieved. The investigation reported here has considered two problems:
