Stress distribution in the abdominal aortic aneurysm (AAA) is about to replace the criterion of the maximum AAA diameter for planning the surgery. The geometry for such FEA is obtained from CT images, where the AAA is shown when loaded by a blood pressure. However, FEA needs a load free geometry as an input. The stress distribution obtained by using the unloaded geometry is more realistic than results obtained by FEA where geometry from the CT is considered to be load free. Several different approaches of how to obtain the unloaded geometry has been published over last years. However, they require to define a new element or even to redefine the FE algorithm itself. We present a simpler algorithm but its major advantage is the use of a commercially available software; it can find the load free geometry of AAAs by using standard elements and regular FE algorithm.
