Fluid-Structure Interaction in a Network of Blood Vessels
Application ID: 660
This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal surfaces producing deformation of the vessel walls.
The complete analysis consists of two distinct but coupled procedures: a fluid-dynamics analysis with the calculation of the velocity field and pressure distribution in the blood (variable in time and in space) and the mechanical analysis with the deformation of the tissue and artery. The material is assumed to be nonlinear and a hyperelastic model is used.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the MEMS Module, Multibody Dynamics Module, or Structural Mechanics Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
