Setting Material Properties

In the freeSurface window, open the Continua node. The color of the Chambers node has turned from gray to blue to indicate that models have been activated.

Open the Chambers > Models node. The selected models now appear within that node.

Open the Multi-Phase Mixture > Fluid Mixture node.

The materials corresponding to each of the mixture components now need to be defined under the Phases node.

Right-click on the Phases node and select New Gas Phase > Air (Air) to create a new node named Air.

Right-click on the Phases node again and select New Liquid Phase > H2O (Water) to create a new node named H2O.

The default material properties for air are suitable but the dynamic viscosity of water needs to be changed.

Select the H2O > Phase Properties > Dynamic Viscosity > Constant node and, in the Properties window, change the dynamic viscosity Value to 0.001002 Pa-s.

Save the simulation.
