Efficient parallel finite-element methods for planetary gravitation: DtN and multipole expansions
Ziheng Yu, Alex D. C. Myhill, David Al-Attar
The Poisson equation governing a planet's gravitational field is posed on the unbounded domain, , whereas finite-element computations require bounded meshes. We imple…

Application of first- and second-order adjoint methods to glacial isostatic adjustment incorporating rotational feedbacks
Ziheng Yu, David Al-Attar, Frank Syvret +1
This paper revisits and extends the adjoint theory for glacial isostatic adjustment (GIA) of Crawford et al. (2018). Rotational feedbacks are now incorporated, and the application…
