| "instruction": "Proceed in Abaqus 2025 Learning Edition through C:\\SIMULIA\\Commands\\abaqus.bat with a command-line or cae noGUI scripting workflow. This task intentionally requires Abaqus because the provided native starting model is an Abaqus CAE database. Start by opening C:\\Users\\user\\Desktop\\task08_block_plate_init.cae; do not create a new model or replace the supplied starting database. The init already contains Steel (E=210000 MPa, nu=0.3), two meshed 3D deformable solids, their section assignments, surfaces, node sets, and positioned instances, but it intentionally has no analysis step, contact interaction, load, boundary condition, assembly-level result-extraction set, or job. Complete this model in the N-mm-MPa system. The Plate spans X=0..24 mm, Y=0..24 mm, Z=0..3 mm and uses a 3 mm structured C3D8R mesh. The Block spans X=8..16 mm, Y=8..16 mm, Z=3..11 mm in the assembly and uses a 2 mm structured C3D8R mesh; its 8x8 mm bottom face initially touches the plate top without clearance or penetration. Add a Static, General step named ContactStep with NLGEOM=ON, initial increment 0.05, minimum increment 1e-6, maximum increment 0.1, and at most 200 increments. Define one finite-sliding surface-to-surface interaction named BlockPlateContact between the plate top main surface and block bottom secondary surface. Use a property named FrictionlessHard with hard normal contact, separation allowed, and frictionless tangential behavior. Encastre the plate bottom. Prevent only block rigid-body drift by fixing U1 and U2 at the supplied BLOCK_ANCHOR node and U2 at the supplied BLOCK_GUIDE node; leave their vertical displacement free. Apply a 2 MPa inward pressure named BlockTopPressure to the 8x8 mm block top in ContactStep. From the supplied instance sets, create assembly node sets named PLATE_BOTTOM_NODES and BLOCK_TOP_NODES for ODB result extraction. Request S, U, RF, and Abaqus contact output sufficient to obtain CPRESS and COPEN. Create and run a one-CPU job named Task08_BlockPlate to successful completion. Save the completed native model and solver result into `C:\\Users\\user\\Desktop\\result`. Derive all metrics from the final ODB frame, not from estimates: max_contact_pressure is the maximum positive CPRESS; vertical_displacement is the minimum U3 on BLOCK_TOP_NODES; reaction_force is the absolute sum of RF3 on PLATE_BOTTOM_NODES; max_mises_stress is the maximum S Mises. Write these four finite numeric fields to C:\\Users\\user\\Desktop\\result\\metrics.json. The total reaction should balance the applied 2 MPa x 64 mm^2 = 128 N load within normal solver tolerance.", |
