HPC mesh segmentation

Before starting any realistic simulation, the numerical mesh, which corresponds to a collection of edges, faces, and connecting points, has to be pre-processed. A key step in this includes mesh segmentation steps, where the mesh is simplified while keeping its main features, which is a computationally daunting task. Here, we employ bleeding-edge quantum algorithms for graph-based problems to improve performance and quality of solutions. This leads to significant benefits, e.g. faster and higher-quality mesh segmentation would considerably improve the preprocessing stage in Total’s classic numerical simulation problems, such as seismic depth imaging and reservoir simulations.
