- One of the computational challenges of recent computer simulations is the representation of complex-shaped objects. Existing commercial software used by industries are mainly based on fitted boundary methods, where the mesh is adapted to the curved boundary. However, numerical approaches in which the boundary is embedded into a fixed mesh have recently gained an increased interest in scientific computing, since the computational burden to generate the mesh is not required. Among broader impacts, the paper is directly beneficial for the research group of Prof. Natalini https://www.researchgate.net/profile/Roberto_Natalini, which aims at representing complex artifacts in monument conservation projects.
