DESCRIPTION:Mesh adaptation is a tool for varying spatial resolution. If a
  topology-deforming approach is taken (i.e.\, mesh degrees of freedom may 
 be added\, removed\, or swapped) then accuracy may be improved - at an inc
 reased computational cost - in regions where a target error estimate value
  is not met. Such an approach also allows computational cost to be reduced
  in regions where accuracy is already sufficient.\nThis seminar focuses on
  topology-preserving approaches\, which can achieve similar aims by simply
  moving the mesh vertices. Whilst less flexible\, parallelism and load bal
 ancing are much simpler to handle and it is possible to avoid interpolatio
 n errors when solving PDEs on a moving mesh. A Python package - Movement h
 ttps://github.com/mesh-adaptation/movement - is presented\, which implemen
 ts several mesh movement algorithms for the Firedrake finite element libra
 ry https://www.firedrakeproject.org/.\n\nThe zoom link is https://cam-ac-u
