Dynamic Pressure on aneurysmal wall
  This Dynamic Pressure is the force pushing on the aneurysmal surface . Dynamic Pressure is about six times different between systole and diastole in unsteady flow. As a result, it is understood that High pressure create (created) on the aneurysmal surface not only at systole condition but also at diastole condition. It indicated that the pulstile flow simulation is very important for blood flow simulation..
