Abstract: Powder coating is a widely used industrial process to obtain functional or aesthetic surface properties on manufactured parts. In a previous contribution we have introduced a Multiphysics methodology to simulate real life coating applications with a Eulerian-Lagrangian solver within the OpenFOAM framework, incorporating multiple periodically moving coating pistols. In the scope of the current study, the aforementioned methodology has been semi-automated to develop the software coatSim. The aim of the software is to provide a sequential work-flow for setting up and simulating practical coating applications for all users, regardless of their expertise in the field of computational science. A database of pre-generated coating chambers and pistol geometries is at the disposal of the user. The database can be complemented by any substrate geometry uploaded. Then the user can interactively perform geometric operations via a combination of Paraview and Python libraries to manipulate STL files. An elaborate meshing scheme allows the user to automatically mesh each of the pistol regions and the coating chamber with the possibility of coarsening or refining the mesh through a single scaling parameter. As the material and process parameters are prescribed, the software performs the necessary operations to set up the case in the correct sequence. The finalized cases are uploaded to the cloud platform KaleidoSim through its extensive API (Application Programming Interface) capabilities in order to perform large series of simulations (e.g.: parametric studies, optimization runs) online. The coatSim software bridges the gap between the practical application and the theoretical expertise required to accurately simulate a coating process in OpenFOAM. Hence, CFD becomes a viable predictive tool for process design in the powder coating industry, as coatSim allows an intuitive workflow without in depth expertise in the field of CFD.
