“…Computations reported in 2001 included aerodynamics of a helicopter [36], fluid-particle interactions in spatially periodic domains [37], parachute FSI for a cross parachute [38], aerodynamics and FSI of a parachute crossing the wake of an aircraft [39,40], and FSI of a T-10 parachute with line pull [41]. A review article published in [42] included ramair parachute flare maneuver, flow around two high-speed trains in a tunnel, flow past a propeller, aerodynamics of a helicopter, fluid-particle interactions of 1000 spheres falling in a liquid-filled tube, fluid-particle interactions in spatially periodic cells, free-surface flow past a circular cylinder, and flow past a dam.…”

In an article published online in July 2018 it was stated that the algorithm proposed in the article is "enabling practical implementation of the space-time FEM for engineering applications." In fact, space-time computations in practical engineering applications were already enabled in 1993. We summarize the computations that have taken place since then. These computations started with finite element discretization and are now also with isogeometric discretization. They were all in 3D space and were all carried out on parallel computers. For quarter of a century, these computations brought solution to many classes of complex problems ranging from Orion spacecraft parachutes to wind turbines, from patient-specific cerebral aneurysms to heart valves, from thermo-fluid analysis of ground vehicles and tires to turbocharger turbines and exhaust manifolds.

“…Adding the wing flaps and winglets to the aircraft model was part of the 1999 PhD thesis of Osawa [17]. The aircraft model with the wing flaps and winglets was used also in computations reported in two 2001 journal papers [18,19] on the aerodynamics and FSI of a parachute crossing the far wake of an aircraft. It is stated in [18] that 'the model has been improved by adding the wing flaps and winglets'.…”

SUMMARYThis paper presents an alternative choice for the construction of integration cells and an additional Lagrange-multiplier mesh in computations using the eXtended finite element method (X-FEM) with the Lagrange-multiplier. The proposed computational target is flow simulations with the Dirichlet boundary conditions on a non-boundary-fitted mesh. The methods studied in this paper make use of a high-order Gaussian quadrature to relax the complexity in implementing the X-FEM with the Lagrange-multiplier. The first of these is the straightforward employment of the Gaussian quadrature as a numerical integration scheme for enriched fluid elements. The second makes use of free Lagrange-multipliers that are not placed at crossing points between fluid elements and the Dirichlet boundary. This method considers the scalability of fluid-structure and fluid-thin object interactions. A unique benchmark problem in which a computational fluid domain is partitioned into two physical domains with the Lagrange-multipliers is introduced to validate the proposed method. Numerical results show that this method is applicable in practice with acceptable numerical accuracy.
