Design and check a steel silo on a shell FEA model: wall courses, hopper, roof, product, wind and seismic loads, legs and anchor bolts.

Frame topology optimisation: choose which members of a dense 3D beam lattice to keep, how thick each is and where joints move.

View ANSYS MAPDL input decks (.inp, .dat, .cdb) in the browser: mesh, supports, loads, DOF counts and mass, without solving anything.

Estimate press force and plastic strain for V-die air bending and three-point bending at once, and run an FEA to see springback.

Open an Ansys Mechanical Condensed Part (.cpa), check it and solve the reduced model for natural frequencies and effective masses.

Assemble a conveyor or machine from a catalogue of parametric parts, join them port to port, and get a bill of materials and checks.

Size belt, chain and gear drives between two shafts: geometry, belt or chain length, side tensions, bearing loads and speeds.

Size a servo axis end to end: motion profile, load through the transmission, motor, gearbox and drive checks, inertia ratio and E-stop.

Size a hydraulic or pneumatic cylinder: push and pull force, barrel wall thickness, rod buckling, bending and cushioning figures.

Crank-angle cycle analysis of a reed-valve reciprocating air compressor: free air delivery, shaft power and the loss once it is hot.

Rigid-body mechanism dynamics in 2D and 3D: joints, drivers, springs, bushings and contact, with the reaction at every joint.

Build a suspension corner from hardpoints, run kinematics and compliance sweeps, and drive a full vehicle over test roads in 3D.

Lay out a pick-and-place cell for a palletiser, six-axis arm, SCARA or gantry, plan a collision-free route and get the cycle time.

Test control logic on a simulated machine before it reaches hardware: Structured Text on a real scan cycle, or your PLC over Modbus TCP.

Parametric 2D sketching with design variables, extrude and revolve to simple 3D parts, and STEP or STL export, in the browser.

Model smooth organic parts from a quad control cage with subdivision surfaces, or wrap a faceted mesh into an editable cage.

A visual node-based 3D modeller: wire blocks together and the geometry rebuilds as you type, with lists, fields and booleans.

A real-time physics workshop: drop machines, material, water and structures on the ground and drive them with the keyboard.

Chess played with simulation blocks: every piece moves by its own law, and you win by taking the other side’s PLC.

Open an STL, see exactly what is wrong with it, repair, edit or sculpt it, and find the orientation that needs least support.

Design gyroid and other TPMS unit cells, fill an STL body with them, and measure the cell's effective stiffness with shell FEA.

Design a variable-pitch infeed or timing screw, watch containers move through it in a rigid-body simulation, and export STL or STEP.

Fill a part with a strut lattice — cubic, BCC, FCC, octet or from points — trimmed to an STL or primitive shapes, and export STL.

Build TPMS or strut-lattice tensile and three-point-bending specimens and solve them with linear FEA for apparent stiffness and modulus.

Write CNC lathe programs from a STEP part, prove them on the bar and against the chuck, and read G-code written for many controllers.

Turn a parametric cabinet or table into parts, fittings, a bill of materials, a cut list and an A4 technical drawing.

Place points, join them with members and get one smooth, closed, printable solid with fleshy junctions, ready to export as STL.

Predict how much heat a heat sink sheds in still air by natural convection and radiation, and find the fin pitch that works best.

Model a frozen-dessert line case by case: freezing time, hardening tunnel, chocolate dipping, extrusion, coating, toppings, cornet line.

Simulate bulk material in transfer chutes, conveyors and screens with the discrete element method, and calibrate it with built-in tests.

Watch a weakly-compressible SPH fluid solver run a dam break checked against Ritter's solution, and a stirred mixing tank.
