In this study is about application of knowledge based start model for die design of automotive body panel using CATIA V5. These days, the automobile industry required short development cycle because customer"s preference is rapidly changed. It"s a reason for using start model. Die design with start model has many advantages, for example, short development cycle, low cost and low design errors, high quality and high productivity, etc. The die design with start model has 4 processes such as prepare design data, input data, replace input data to start model and design start with application of start model.

In this paper, a nonlinear one-dimensional finite element model is developed for the human arteries conveying pulsatile blood. The finite element model is formulated from the nonlinear one-dimensional governing equations for the human arteries represented by axially expandible elastic tubes. Various flow profiles are considered to numerically investigate the blood pressure and flow rate through an ascending aorta with slowly narrowing cross-section.
