The TAFSM has recently created the Institute for Frontier Fluid-Structure Interaction Analysis in Green Computing Systems Research Organization at Waseda.
The institute will strengthen TAFSM’s position in innovating powerful computational analysis methods and bringing solution to a wide-range of real-world problems that no one else, or very few, in the world can solve.

The ST-SI-TC method is based on ST-SI and ST-TC methods combined.
The ST-SI-TC method we introduce here integrates the ST-SI and ST-TC methods in the ST-VMS framework. It enables accurate flow analysis when we have a spinning solid surface that is in contact with a solid surface.

The ST-SI method can handle spinning structure of subdomains without remeshing.
The method is intended for fluid-structure interaction (FSI) analysis where one or more of the subdomains contain spinning structures, such as the rotor of a wind turbine, and the subdomains are covered by meshes that do not match at the interface and have slip between ...

Thermo-fluid analysis of a truck under road condition.
In this thermo-fluid analysis, we use a road-surface temperature higher than the free-stream temperature, and a tire-surface temperature that is even higher. We also include in the analysis the heat from the engine and exhaust system, with a reasonably realistic representation of the rate by which that heat ...

We present computation for an aortic valve with coronary arteries.
The computation demonstrates that the ST-TC method can bring interface-tracking accuracy to fluid mechanics of heart valve, and can do that with computational practicality.

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 ...
