Klucki

Paint a plate from real materials and watch 👀 heat spread through it. Klucki is a small lab for heat conduction. You paint a plate, set its edges, press play ▶️ and watch 👀 heat move through it. Pick a material and drag ✋ across the grid to lay it down. Ten materials are built in, from copper and aluminium to brick, pine and foam. You can add custom ones. Mark cells as hot or cold, then set each edge as fixed, insulated or exposed to the air. Press play ▶️ and the plate fills with colour. Isotherm lines show where the temperature is equal. Switch the view between temperature, material and heat flux. Pause ⏸️, step or reset at any time ⏱️. Klucki shows how far the run is from steady state and how long it will take. Place probe pins on the plate and read their temperature curves over time ⏱️. Draw a cut line to see 👀 a temperature profile across the plate. The ledger shows heat in, heat out and heat stored, with a flow chart 📊 for every boundary. Not sure where to start 🚀? Load one of twelve experiments, such as a cooling fin, a copper bus bar, a hot spot or an insulated wall with a thermal bridge. What you can do: - Paint plates with brush, rectangle, fill and seed tools 🛠️ - Browse a catalogue of materials with conductivity values - Run, pause ⏸️ and step the simulation - Read probes, cut lines and the heat ledger - Log 📝 runs and compare ⚖️ two of them side by side - Follow trends 📈 in time ⏱️ to steady state Klucki suits students, teachers and anyone curious about how heat travels.
