• Structural dynamics Eurocoder Masonry houses checked to the Eurocodes. Draw walls, openings, slabs and the roof storey by storey, and the house is solved in 3-D under its own weight, imposed loads and the snow, wind and earthquake of its site. The walls, footings, slabs, lintels and rafters are checked against EN 1990 to EN 1998 with the trace of every value, and the whole is written up as a calculation report. A demonstration: not for construction. Open simulator →
• Structural dynamics Modal Analysis Natural frequencies and mode shapes of a 3-D solid part, free-free (unsupported, as if hanging on a thread). Start from a steel tuning fork tuned to A4 (440 Hz) or upload your own STL, pick the material, and the part is meshed automatically with quadratic tetrahedra. Produces an animated 3-D view of every vibration mode, which you can also listen to. Open simulator →
• Pipes & geothermal Pipe Network 1D (Next-Gen) Transient pipe-network simulation on the next-generation FlowPhys 1D solver. Draw the network in the visual editor or define it in code; add pumps, valves, heat exchangers, thermal energy storage and PID-controlled devices, with per-node boundary conditions and time schedules. Single- and two-phase flow, heat transfer, and water chemistry with calcite scaling and sand erosion — validated against analytic benchmarks and geothermal field cases. Open simulator →
• Photonics Photonic Waveguide Mode Explorer Guided light in a photonic waveguide cross-section, from the mode solver to a working sensor. Every mode is labelled (TE0, TE1, TM0) with its effective index, the share of its light in each material and a field map, and a 3-D view of the chip shows it travelling along the guide. Model a bare core, a passivated core or a responsive coating, sweep the medium or coating index for the bulk sensitivity, and read the chip out as a Mach–Zehnder or bimodal interferometer: phase slope, fringes and detection limit.

• Structural dynamics Flying Spaghetti Free-flying beam benchmark (Tomec & Jelenić 2024): a generalised-force impulse sets a free-free beam into 3D flight. Produces an animated trajectory of the beam centerline. Open simulator →
• Metal forming Metal Stamping Axisymmetric sheet forming: a flat metal disc is stamped between two matching rigid dies into a user-drawn profile, then the tool lifts and the sheet springs back to its permanent shape. Finite-strain plasticity with Voce hardening; produces an animated section mesh with von Mises stress and plastic strain fields. Open simulator →
• Structural dynamics Frame Studio Planar frame statics on a geometrically-exact Reissner beam: draw joints and members, pin or clamp supports, and apply point and distributed loads. The frame is pushed into the large-deflection regime load step by load step, producing an animated deformed mesh with a per-node bending-stress field. Open simulator →
• Topology optimization Topology Optimizer 3D topology optimization for additively-manufactured parts. Specify a rectangular design domain, load, and supports; the solver minimizes Techno-Economic Cost (TEC) under a smooth high-cycle fatigue penalty using sparse FEM + SIMP + MMA, returning a print-ready binary geometry plus its continuous density field.
