• TAFSM creates the Institute for Frontier Fluid-Structure Interaction Analysis
    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.

  • Next FSI Short Course
    The next FSI short course will be in San Diego. See more details.
  • Space–Time Slip Interface and Topology Change (ST-SI-TC) method
    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. See more details .
  • Space–Time Slip Interface (ST-SI) method
    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 ground vehicle and its tires
    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 ...
  • Textbook on computational FSI authored by Takizawa has been translated to Japanese
    Wiley textbook on computational FSI, authored by Takizawa has been translated to Japanese by Morikita Publishing Company. See here for more details.
  • Flapping-wing aerodynamics with wing clapping
    Flapping-wing aerodynamics of an MAV with wing clapping. In the analysis, the wings are brought into an actual contact when they clap. See more details .
  • Fluid mechanics computation of heart valve
    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. See more details .
  • 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 ...
