CADEngBench - Physics Reach (L3): leaderboard
The physics level of CADEngBench (MBZUAI, 2026): generated parts are analysed with CalculiX linear-static FEA under fixed material, supports and loads. Reach is the percentage of the 164 eligible parts whose generated geometry reaches a completed solve; higher is better.
Metric: FEA reach rate (%; share of the 164 L3-eligible generated parts whose geometry reaches a completed CalculiX linear-static solve under the benchmark's fixed material, supports and loads; reaching a solve does not require matching the reference response). Source: arxiv.org. Saturation forecast: Around March 2027. 8 models tracked.
