There are no line sources. You could create a series of point sources, or create a long thin boundary and apply a boundary source.

Normally you would imprint a face back in DesignModeler so that you had a 2D mesh region to pick in CFX-Pre. You could use the Edit Mesh tools in CFX-Pre (see doc), but you can obviously only pick existing element faces.
