Hi,
I am working in what is called the "Backstep" problem, which is basically simulating fluid flow inside a pipe connected to a block-shaped tank (modeling one eight of the geometry). I am sort of following instructions given in a workshop, but I ran into a complication. Apparently, after creating the geometry with the CAD tools in COMSOL I need to create a workplane, then a Bezier polygon, and then extrude the workplane, before creating an intersection(this to end up with the one eight of the original geometry created, I think). Though, when Extrude the workplane, I then change the Distance from Workplane and "Build Selected", but I get an error message saying that I need to input the objects. But when I go back and try to select the workplane, I can't. It just does not want to be added.
Do you have any clue as to why is this happening?
