Abstract Scope |
ROM-net reduced order modeling (ROM) is applied to finite element thermo-mechanical simulation of metal additive manufacturing. This is a significant challenge due to the continuously evolving computational domain on which a local reduced basis is required to apply a ROM-net. The support of local reduced bases is closely related to the sampling of mechanical predictions. Considering the modeling of a directed energy deposition process, it is proposed to organize the training set of simulation snapshots according to an energy deposition length that represents the progress of the process. When the projection-based ROM-net is applied to the full-order model, the simulation data sequence allows the design of a local ROM depending on categories of input parameters. The similarity of data in a category is evaluated by a Grassmann distance between local reduced subspaces. The simulation of the construction of a turbine blade showed a computational speedup of about 100. |
