[[$Boundary]] orand [[$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
