AN ITERATION-FREE, PARTITIONED METHOD FOR SOLVING COUPLED PROBLEMS

Coupled problems consist of two or more problems which in most cases describe different physical phenomena. An example of such a problem is the interaction of fluid and structure. Usually, the most accurate way to solve coupled problems is the monolithical approach. But often, due to different reasons, a partitioned method is used, where the subproblems are solved with different software packages and there may be different discretisation methods. One reason for partitioning a coupled problem is that existing codes and the best discretisation schemes can be used. In this note we introduce an iteration-free, partitioned method which is based on a linear-implicit time integration method.
