BC_Type = FreeSurface: This boundary imposes zero normal velocity at the surface.

Syntax for this boundary condition:

FreeSurface Boundary_Name { ( Temperature Tfs | HeatFlux = qfs | ConvCoeff = hc, ConvTref = Tinf ) }

 

Variable Name

Description

Valid Data Types

Temperature (Tfs)

Static temperature

CONSTANT, EXPRESSION f(x,y,z,t)

HeatFlux (qfs)

Magnitude of surface heat flux

CONSTANT, EXPRESSION f(x,y,z,t)

ConvCoeff

Convective heat transfer coefficient

CONSTANT, EXPRESSION f(x,y,z,t)

ConvTref

Outside temperature

CONSTANT, EXPRESSION f(x,y,z,t)

 

If MeshUpdate analysis is being done, the FreeSurface boundaries are allowed to move to remain tangent to velocity vectors.
