Many engineering systems require accurate simulations of complex physical systems, but analytical solutions are only available for simple problems. To balance computational speed and accuracy, adaptive meshing techniques are used, allocating more resources to critical parts of the geometry. The Adaptive Meshing By Expert Reconstruction (AMBER) approach views mesh generation as an imitation learning problem, combining a graph neural network with online data acquisition to predict the projected sizing field of an expert mesh on a given intermediate mesh. This iterative process ensures efficient and accurate imitation of expert mesh resolutions on arbitrary new geometries during inference.
Low GrooveSquid.com (original content) Low Difficulty Summary
Engineers need ways to accurately simulate complex physical systems. Right now, they use numerical methods like the Finite Element Method (FEM), but these can be slow or inaccurate. A new approach called AMBER makes it easier to create detailed models by “learning” from expert meshes. This means that AMBER can quickly generate accurate models of new shapes and sizes, which is useful for many real-world applications.
