In several areas of science and engineering, STL (STereoLithography) data files are the standard representation of three-dimensional geometries. STL files are amenable to 3D printing and computer-aided design modeling, which often become the starting point for high-fidelity Finite Element analysis simulations. When the model is complex and involves various STL files, their integration into a conforming mesh with CAD-based interface level of definition is not a straightforward process. In this paper, we present I-STL2MOOSE, a Python-based tool that combines an arbitrary number of STL files into an integrated volumetrical mesh that is directly readable by MOOSE, a parallel, efficient open-source Finite Element implementation.
