Środowiskowe Seminarium Fizyki Atmosfery

Over the last three years, in the aerosol-cloud modelling team at IGFUW (group of Hanna Pawłowska) we have been developing a new free/libre and open-source C++ library: libmpdata++. The project is carried out in collaboration with Piotr Smolarkiewicz (ECMWF) and it aims at implementing the MPDATA family of numerical solvers using novel programming techniques that help to improve researchers' productivity(researchers being both the users and developers of the software).During the seminar, we will briefly introduce the library features included in the 1.0 release of the library which accompanied publication of the library manual in the Geosci. Model Dev. journal (Jaruga et al., 2015; doi: 10.5194/gmd-8-1005-2015).We will then report on what new features the past months of development have brought to libmpdata++. These features are aimed for the upcoming 2.0 release and include:- higher-order operators (for DNS/iLES simulations);- implicit treatment of absorbers (for immersed-boundary method);- adaptive timestepping;- distributed-memory parallelisation using MPI.
