ScienceSkills

Comprehensive TorchSim / torch-sim atomistic simulation skill for molecular dynamics, relaxation, high-throughput MLIP workflows, trajectory generation, trajectory analysis, validation, and movie production for materials systems.

Run simple dimensionless 1D Euler-Bernoulli beam mechanics with selectable boundary conditions, point forces, distributed loads, point moments, springs, plots, CSV/JSON results, and deformation GIFs. Use when asked to analyze a simple beam, cantilever, fixed-fixed beam, overhang, support reactions, shear/moment/deflection plots, or a small educational beam mechanics movie/artifact.

Create high-resolution Chladni plate resonance visuals and animations from analytic vibrating-plate mode superpositions. Use when asked for Chladni figures, nodal-line sand patterns, sound-wave or resonance visualization, vibrating square/rectangular/circular plates, cymatics-inspired scientific art, physics demonstration images, or GIF movies of plate dynamics. Produces text-free PNG images, GIF animations, frame sequences, field data, parameters JSON, captions, and README by running a bundled Python renderer.

Run fast 2D SIMP topology optimization with flexible boundary conditions, lightweight STL exports, and optional STL turntable renderings. Use when asked to optimize cantilevers, beams, bridges, plates, tension/shear strips, custom support/load layouts, density fields, compliance minimization, profile/flat/multimaterial STL meshes, polished STL previews, or rotating GIFs of optimized geometry. Produces density plots/data, boundary-condition previews and resolved node/DOF JSON, optimization history, summary files, optional STL meshes, and optional STL render artifacts by running bundled Python scripts.

Run parameterized 2D lattice fracture simulations from the Fracture and Mechanics notebook as offline artifacts. Use when asked to simulate a pre-cracked triangular lattice, Mode I tension, Mode II shear, Morse/Lennard-Jones/MLIP pair potentials, temperature effects, strain-rate effects, crack propagation, stress-strain curves, or fracture movies. Produces an animated movie, stress-strain plot, final lattice image, CSV data, JSON run metrics, and README by running a bundled Python script.
