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.
