SUMMARY:Some open problems in solid-Earth dynamics associated with the flu
 id outer core and oceans - David Al-Attar\, DES\, University of Cambridge
DTSTART:20251017T150000Z

CONTACT:Duncan Hewitt
DESCRIPTION:Over the time-scales of seconds to years that are associated w
 ith processes such as seismic wave propagation\, tidal deformation\, and r
 otational variations\, the Earth's crust\, mantle and inner core are visco
 elastic solids\, while the outer core and oceans are compressible fluids w
 hose viscosity's are sufficiently low as to be commonly neglected. Were it
  not for the presence of the fluid regions\, an essentially complete mathe
 matical description of the dynamics could be developed\, and the numerical
  solution of the resulting equations would present no essential difficulti
 es. In this talk I will discuss some of the remaining challenges\, both th
 eoretical and computational\, that arise within these applications due to 
 the presence of fluid regions and point to some possible methods for their
  resolution.\n
