Abstract
In patient-specific arterial fluid-structure interaction (FSI) computations, the image-based artenal geometry comes from a configuration that is not stress-free We present a method for estimation of element-based zero-stress (ZS) state The method has three main components, and we present one of them. An element-based mappmg between the artenal and straight-tube configuration is used for mappmg from the artenal configuration to the straight-tube configuration, and for mapping the estimated ZS state of the straight tube back to the artenal configuration, to be used as the initial guess for the iterative method that matches the image-based target shape We present a set of test computations to show how the method works
