Summary

• What is new: NITO introduces a novel, resolution-free, and domain-agnostic approach to topology optimization in engineering using deep learning, notably outperforming existing models in efficiency and speed.
• Why this is important: Topology optimization in engineering is challenging due to the need for optimal material distribution for maximum performance, which often requires time-consuming and computationally expensive methods.
• What the research proposes: NITO employs deep learning to accelerate the topology optimization process, leveraging a novel method, BPOM, to handle boundary conditions efficiently and without the limitations of prior models.
• Results: NITO achieves up to seven times better structural efficiency than state-of-the-art diffusion models while being significantly faster and more versatile in application across different domains.
