-The 3D calving model is significantly more complex and computationally demanding than the 2D case,  due to the comparative difficulty of identifying calving events in a 3D domain ([[solvers:calving3d|Calving3D]]), as well as the requirement for complete remeshing following calving events ([[solvers:remesh|Remesh]]). The theory and implementation of the 3D calving model are described in the publication: [[https://doi.org/10.1002/2017JF004349|A Full‐Stokes 3‐D Calving Model Applied to a Large Greenlandic Glacier]].+The 3D calving model is significantly more complex and computationally demanding than the 2D case,  due to the comparative difficulty of identifying calving events in a 3D domain ([[solvers:calving3d|Calving3D]]), as well as the requirement for complete remeshing following calving events ([[solvers:remesh|CalvingRemesh]]).

 A 3D test case can be found at elmerice/Tests/Calving3D. Out of the box, this test is likely to **fail** due to an issue with gmsh (see External Dependencies below) A 3D test case can be found at elmerice/Tests/Calving3D.

 +Recently, Joe Todd & Eef van Dongen have been working on overhauling/improving the 3D calving model using [[https://www.mmgtools.org/|MMG]]. This involves 2 new solvers, [[solvers:remeshmmg|CalvingRemeshMMG]] and [[solvers:calvinglset|Calving3D_lset]], which replace CalvingRemesh and Calving3D, respectively.
