Boundary Selection and Identification

There are two main ways to select boundaries. When you already know the boundary (block) id:

Select your mesh in the Pipeline Browser
If the Selection Inspector isn't active, turn it on "View -> Selection Inspector". This usually shows up in the lower left part of the ParaView window, under the Object Inspector.
If you know the surface ID ("composite ID"),
1. Set "Selection Type" to "Blocks", and "Field Type" to "CELL".
2. In the Selection Inspector (scroll down if needed), check "Blocks", and then check/uncheck whichever blocks you care about. You will see those corresponding surfaces in the 3D view highlight as a pink wireframe collection of triangles.
if you don't know the surface ID, but want to find it out by mousing on the mesh, you can use "Edit -> Select Block", (or just hit the "b" key), and then use the mouse to drag out a rectangular region on the mesh which surrounds a portion of the surface(s) of interest.
1. Selected boundaries will highlight as pink wireframe triangles, and the selected blocks will be checked in the Selection Inspector, telling you the ID(s) of interest.
2. if you got too many blocks, you can check/uncheck blocks in the selection inspector.
