Understanding Thermal Boundary Condition Sets
When you create a boundary condition in Thermal, the software adds it to a boundary condition set (BC set). A BC set is a collection of boundary conditions that act together, and at the same time, on your model. For more information, see Guidelines for Thermal Boundary Condition Sets.
You can manage your BC sets with the BC Sets dialog box. When you click Home > Boundary Conditions > Boundary Condition Sets, this dialog box opens with the following options:
New—Opens the BC Set Definition dialog box. Enter a name and optional description for the new boundary condition set.
* 
You can also access the BC Set Definition dialog box by clicking New in the Member of Set area on the Prescribed Temperature and Convection Condition dialog boxes.
Copy—Creates a copy of the highlighted boundary condition set and adds it to the list.
Edit—Opens the BC Set Definition dialog box with the information you used to specify the highlighted boundary condition set.
Delete—Removes the highlighted boundary condition set.
Description—Displays the optional description you entered when you created the boundary condition set.
If you want the flexibility of treating each of your boundary conditions separately, use a unique name and set name for each boundary condition. However, remember that a thermal analysis can only use one boundary condition set.
Heat load and BC sets provide a logical means of organizing your modeling entities so you can define analyses effectively and clearly. A carefully considered approach to heat load and BC set creation simplifies heat load and boundary condition selection when defining your analyses. Although the software permits you to create each heat load and boundary condition as a separate heat load set or BC set, you can reduce the number of selections you need to make for analysis definition by grouping your heat loads and boundary conditions into sets.
