Space–Time Topology Change (ST-TC) method
The ST-TC method can handle an actual contact between the solid surfaces as an interface-tracking method.
The challenges include contact between moving solid surfaces and other cases of topology change (TC), such as those in cardiovascular FSI, parachute FSI, and flapping-wing aerodynamics. As shown in the movie we are comfortable with concluding that the ST-TC method has the interface-tracking accuracy, the TC flexibility, and the computational practicality.
