“…One major difference exists between the VLM and VPM implementations that are covered here: Whereas our VLM solver is used to generate steady-state solutions, the VPM solver is inherently transient due to the vortex particle nature of its wing wake model. Interested readers are referred to the related work by Anderson et al [15], which goes into more detail and uses the coupling approach presented in this work.…”

“…We do not give results for this implementation in this work. Instead we would like to refer the interested reader to the companion paper by Anderson et al [15], where a more elaborate treatment of the specifics of the solid and fluid solvers and this example are given.…”

“…The first of the solid models used in this work is a "classical" FEA implementation of the Reissner-Mindlin shell model with FEniCSx. For more information on this shell model the reader is referred to [15,18]. A central feature of FEA-type discretizations is its precise definition of the bases in which variables are expressed.…”

Recent advances in Multidisciplinary Design Optimization (MDO) have opened up the possibility of solving large-scale MDO problems with appropriate computational tools. One way in which design space exploration in MDO problems is made possible is by using solvers with varying levels of fidelity and computational cost. Our aim in this work is to make possible such an MDO approach by establishing a solver-independent aeroelastic coupling approach. We show that conservation of aeroelastic work requires an algebraic relation to be satisfied that involves the projection operators which map displacements and forces between solvers and states. Implementation examples are given for various combinations of fluid and solid solvers, and it is shown that these implementations indeed conserve all force components and aeroelastic work.
