For 2-D problems, you can create 2-D geometry via the constructive solid geometry (CSG) or the geometry function approach. Using the CSG approach, you can use a set of solid building blocks (square, rectangle, circle, ellipse, and polygon) and combine them to define complex geometries. For details, see Create 2-D Geometry.
The PDE Modeler app uses the CSG approach. For details, see Create 2-D Geometry in the PDE Modeler App.
