The inception of the Space–Time Isogeometric Analysis (ST-IGA) in 2010 was major milestone in the Space–Time Computational Flow Analysis (STCFA). It enabled first-of-its-kind solutions in many classes of problems ranging from flapping-wing aerodynamics of an actual locust to tsunami-shelter vertical-axis wind turbines, ventricle-valve-aorta flow analysis to car and tire aerodynamics with near-actual geometries, road contact, and tire deformation. We will provide an overview of how the ST-IGA evolved in the solutions it can deliver in connection with the STCFA and reached where it is in 2024. We focus on tire aerodynamics with complex tread pattern and rod contact as one of the latest examples of what the ST-IGA can do now.
