Axisymmetric fluid-structure interaction model of the left ventricle

Publisher Summary This chapter demonstrates the feasibility of a commercial finite element code in a linear elastic axisymmetric fluid-interaction model of the left ventricle. A fluid-structure interaction model of the left ventricle and the immersed boundary method have proven to be very useful tools in ventricular modeling, the greatest limitation is the in-house development of the code, limiting its widespread use among cardiac mechanics research groups. Therefore, researchers make use of a commercial code and extend its capabilities through customized user-supplied coding to allow the modeling of the active behavior of cardiac tissue. While a fluid-structure interaction model of diastolic filling was not possible in the past through a commercial code, researchers have demonstrated the feasibility of ADINA in cardiac modeling.
