# Proof of Concept test for Electric Water Heater

This animation shows a proof of concept geometry that we realized for an electrical water heater.

Two graphite electrodes are immersed in a water tank. Three physics are involved. First, the **static current conduction** equation is resolved. Then, **Joule heating energy** is calculated in the entire geometry and used as a body force for the **heat equation**. Finally, temperature calculated is introduced in the **Navier-Stokes equations**
