I have been trying to simulate a blood flow inside a vein in which I have assumed the vein as a simple curved pipe. In the geometry section the cylinder option is meant only for straight and hollow cylinders. How to model a curved pipe in comsol 4.3b?

Hello Chachin,
As Lasse suggested, a fraction of a torus could work for you in some cases. A more general solution is to sweep a disc along a curve (be it a polygon, parametric curve or an interpolation curve, etc). See the attached screenshot.
