Eruptis Walmi

Paint a plate, heat one edge and watch 👀 how heat spreads through it. Eruptis Walmi is a heat lab for your phone 📱. You build 🔨 a square plate out of different materials, heat or chill its edges and watch 👀 the temperature spread across it. Paint the plate with copper, aluminium, carbon steel, granite, brick, glass, water, pine, EPS foam or still air. Cut a void to block the heat. Pin edges hot or cold, then place probes where you want a reading. Press run and the plate fills with colour and labelled contour lines. Step through the simulation one frame at a time ⏱️, or fast ⚡-forward until it settles. When the plate reaches steady state, you see 👀 how long it took and the final temperature at each probe. What you can do: - Start 🚀 from seven ready-made plates, such as a copper fin, a window pane, a heat-sink comb or a cracked plate. - Browse the material list 📋 and compare ⚖️ how fast ⚡ each one conducts heat. - Save 💾 your own plates with a name and notes 📝, and load them back to the bench later. - Read probe temperature curves over time ⏱️ for every run. - Compare ⚖️ time ⏱️-to-steady across all your runs in the run log 📝, and use the quick benchmark to time a preset. - Learn 📖 the basics in the field guide, which has a live rod demo and short notes 📝 on diffusivity, edges, isotherms and stability. Eruptis Walmi suits students, teachers and curious people who want to see 👀 why ❓ copper warms fast ⚡ and foam holds heat. Try a plate, change one material and watch what happens. Open Eruptis Walmi, pick a preset and press run.
