The objective of this work is to develop and validate a numerical model to study wetting during the
impact of millimeter-size drops on a flat, smooth, solid substrate under isothermal or non-isothermal
conditions. A finite-element modeling is used to simulate the transient fluid dynamics and heat transfer,
