Beyond Static Meshes in preCICE
Please login to view abstract download link
preCICE is an open-source coupling library for partitioned multi-physics simulations. It provides a flexible framework for exchanging mesh-based data between different simulation codes, enabling the simulation of complex multi-physics problems involving multiple solvers. These solvers may run on massively parallel systems with large meshes partitioned among their ranks. To facilitate leveraging these parallel systems, preCICE used to require solver meshes to remain static during the simulation. In this talk, I present an overview of various use-cases for non-static meshes and describe how to realize them in preCICE using various existing methods, including static-reference domains, just-in-time mapping schemes, encapsulation of dynamic behavior in the adapter, and resetting the mesh definitions of preCICE during runtime.
