$Boundary orand $ThermalBoundary are the same commands. This command setup the thermal boundary of 3D thermal solver. The format is

$Boundary
N_surface_number
Surface_No_1  Surface_type  Surface_value
Surface_No_1  Surface_type  Surface_value
Surface_No_1  Surface_type  Surface_value
Surface_No_1  Surface_type  Surface_value
.....
.....  repeat N_surface_number

Surface_No: The gmsh surface number to set as thermal boundary
Surface_type:  value: 1: fix temperature boundary  2: convention boundary condition
Surface_value: The coefficient at the boundary. For type 1, it is the surface potential  For type=2, it is the thermal convention coeffcient

For example

$Boundary
3
123  1  300.0
221  1  400.0
224  2  22.3
