The video tutorial introduces transient thermal analysis and explores phase change processes, including melting, solidification, boiling, condensation, sublimation, and deposition. It explains molecular behavior and energy changes during phase transitions and demonstrates how to simulate phase change using ANSYS Mechanical. The tutorial also highlights industrial applications of phase change, such as soldering, casting, and 3D printing.
