A new adapter of the weather numeric prediction software Weather Research and Forecast (WRF) model<br/>
<p>Zhen Wu, Sun Yat-sen University, China</p>
MaMiCo-preCICE coupling for hybrid molecular-continuum flow simulations<br/>

</summary>
<p>In the field of geoscience, the full knowledge of atmospheric conditions is necessary in the fields of urban planning, disaster mitigation, emergency response and air pollution assessments. While we see the remarkable advantages of the meso-scale model of Weather Research and Forecast (WRF) in the simulation of the atmosphere, it shows significant deficiencies in describing the micro-scale effects of the complex underlying surface. For solving this problem, a new adapter is developed based on preCICE. Thanks to the open source nature of the WRF model, the developed adapter enables the WRF to be coupled with other widely used Computational Fluid Dynamics (CFD) software, such as OpenFOAM. In fact, the developed adapter aims to provide the WRF model the Fluid-Fluid coupling capacity, which could be used to conduct a trans-scale numerical simulation downscaling the results from a numeric weather prediction software to drive a micro-scale (~1m) flow simulation. Such a trans-scale simulation shows the detailed flow structures inside the urban boundary layer or above complex hilly terrain.</p>
<p>Molecular-continuum flow simulations apply computationally intensive molecular dynamics (MD) simulations in localized regions of a geometry under consideration, and classical, computationally cheaper computational fluid dynamics (CFD) solvers are employed for the remainder of the vast computational domain. The macro-micro coupling tool MaMiCo handles the coupling between a MD solver and a CFD solver. It is highly parallelized and provides interfaces to couple various MD and CFD solvers.
Recently, preCICE has been coupled to MaMiCo. It allows us to access the large number of CFD solvers already coupled to preCICE, to use preCICE's interpolation methods in case of non matching grids between MaMiCo's grid and the continuum software's grid, to have a real partitioned approach with separate executables, to use preCICE's advanced time coupling schemes, etc. Validation and scaling have been done on various super computers, generally on a Couette flow scenario. Furthermore, MaMiCo and preCICE have been recently used to simulate an advanced transcritical multiphase scenario. Finally, we used preCICE to couple a CFD solver running on a laptop to a massively-parallel MD simulation running on a cluster.
