Alexander Shukaev: A Distributed Communication Model for the Code Coupling Library preCICE
Precise Code Interaction Coupling Environment (preCICE) is a coupling library for partitioned simulations of multiphysics scenarios. Its current release version only offers a centralized communication model (CCM) between processes of coupled solvers, that is they communicate in a client/server manner. Performance testing on massively parallel systems has confirmed that this approach results in a data throughput bottleneck (on servers), which leads to a dramatic loss of scalability. The potential solution to this problem is to develop a distributed communication model (DCM) that would be based on a parallel process-to-process communication approach. In this talk, I will present the corresponding software engineering challenges, their goals and solutions.
Viacheslav Mikerov: Using a Fixed Grid Finite Difference Flow Solver for Partitioned Fluid-Structure Interaction
The research is dedicated to the partitioned Fluid-Structure Interaction (FSI) approach with a minimal invasive software design using PreCICE (Precise Code Interaction Coupling Environment) library. A specific goal of this work is to present such a fluid flow solver on a fixed grid using a finite different discretization which can interact with different structure solvers. One of the challenges here is to handle moving or deforming bodies with complex surface geometry embedded in a fluid flow.
