Geometry-Preserving Reduced-Order Modeling via Immersed Tensor Decomposition (ITD)
ITD combines a signed-distance geometry representation, a body-fitted function Φ for exact Dirichlet conditions, and Tucker decomposition within C-HiDeNN-TD to enable separable reduced-order modeling on Cartesian background meshes.
