Abstract
Fluid mechanics computation of a heart valve with an interface-tracking (moving-mesh) method was one of the classes of computations targeted in introducing the space-time (ST) interface tracking method with topology change (ST-TC). The method was introduced with finite element descritization. Now, we apply the method to isogeometric analysis (IGA) to calculate more accurate computation, and simplify the master-slave system in ST-TC method towards fluid-structure interaction (FSI) analysis.
