A shape optimisation of mutual inductances among coils
Toru Takahashi, Tatsuya Tokito, Yi Cui +1
This paper introduces a shape optimisation framework for achieving desired mutual inductances (MIs) among coils in 3D space. Utilising a wire modelling approach, the coils are disc…
A shape optimisation with the isogeometric boundary element method and adjoint variable method for the three-dimensional Helmholtz equation
Toru Takahashi, Daisuke Sato, Hiroshi Isakari +1
This paper presents a shape optimisation system to design the shape of an acoustically-hard object in the three-dimensional open space. Boundary element method (BEM) is suitable to…
An isogeometric boundary element method for three-dimensional doubly-periodic layered structures in electromagnetics
Toru Takahashi, Tetsuro Hirai, Hiroshi Isakari +1
This paper proposes an isogeometric boundary element method (IGBEM) to solve the electromagnetic scattering problems for three-dimensional doubly-periodic multi-layered structures.…
Parallelization of the inverse fast multipole method with an application to boundary element method
Toru Takahashi, Chao Chen, Eric Darve
We present an algorithm to parallelize the inverse fast multipole method (IFMM), which is an approximate direct solver for dense linear systems. The parallel scheme is based on a g…
