• Generalized wave propagation problems and discrete exterior calculus 

  Räbinä, Jukka; Kettunen, Lauri; Mönkölä, Sanna; Rossi, Tuomo (EDP Sciences, 2018)

  We introduce a general class of second-order boundary value problems unifying application areas such as acoustics, electromagnetism, elastodynamics, quantum mechanics, and so on, into a single framework. This also enables ...

• Discrete exterior calculus and exact controllability for time-harmonic acoustic wave simulation 

  Myyrä, Mikael (2023)

  Diskreetti ulkoinen laskenta (engl, discrete exterior calculus, DEC) on differentiaaliyhtälöiden ratkaisemiseen soveltuva diskretointimenetelmä, joka säilyttää tiettyjä fysikaalisten mallien geometrisia ominaisuuksia ja ...

• Systematic implementation of higher order Whitney forms in methods based on discrete exterior calculus 

  Lohi, Jonni (Springer, 2022)

  We present a systematic way to implement higher order Whitney forms in numerical methods based on discrete exterior calculus. Given a simplicial mesh, we first refine the mesh into smaller simplices which can be used to ...

• Discrete exterior calculus and higher order Whitney forms 

  Lohi, Jonni (2019)

  Partial differential equations describing various phenomena have a natural expression in terms of differential forms. This thesis discusses higher order Whitney forms as approximations for differential forms. We present ...
