+PhysArena is a benchmarking suite for physics-based machine learning.
+
+PhysArena provides standardized benchmarks with fixed evaluation protocols, metrics, and splits to enable fair and reproducible comparison of models on physical problems.
+
+All datasets are distributed in the PLAID format, ensuring a uniform, structured representation across benchmarks and seamless interoperability with the PLAID ecosystem.
