Free-surface modelling
{{Short description|Numerical modeling technique in fluid dynamics}}
{{Unsourced|date=August 2014}}
In computational fluid dynamics, free-surface modelling (FSM) refers to the numerical modelling of a free surface—a freely moving interface between immiscible fluids—in order to be able to track and locate it.
Common methods used in free surface modelling include the level-set method and the volume of fluid method.
