+## Overview
+
+Sandwich I-beam optimization for a test fixture. Steel construction with lightening holes in the web. Goal: reduce mass from ~974 kg while meeting displacement (≤ 10 mm) and stress (≤ 130 MPa) constraints.

+## Open Tasks
+
+- ❓ G1: Beam length and support conditions
+- ❓ G2: Loading definition (point? distributed? self-weight?)
+- ❓ G3: Displacement measurement location and DOF
+- ❓ G4: Stress constraint scope (whole model? exclude supports?)
+- ❓ G5: Geometric feasibility of hole patterns at extremes
+- ❓ G6: Result sensors in Beam_sim1.sim
+- ❓ G7: NX parametric rebuild reliability across full range
+- ❓ G8: Mesh type, density, convergence status
+- ❓ G9: 130 MPa stress limit basis (yield? safety factor?)
