DESCRIPTION:Finite-Element Sea-ice Ocean circulation Model (FE
 SOM) uses unstructured triangular meshes and is em
 ployed either as standing-alone global ocean model
  or as part of FESOM-ECHAM5/6 coupled setup. Sever
 al examples pertaining to studies focused on polar
  oceans will be given to characterize the potentia
 l of FESOM and also to indicate typical difficulti
 es related to the strongly variable resolution. \n
 \nBrief intercomparison of FESOM to a global cell-
 vertex finite-volume setup is presented. While it 
 is more numerically efficient than the finite-elem
 ent setup of FESOM\, it requires special measures 
 to maintain stable performance because of its too 
 large velocity space. Most effective stabilization
  is provided by either computing the momentum adve
 ction on scalar (median-dual) control volumes\, or
  making use of the vector-invariant form. Both app
 roaches effectively trim the nonlinear term in the
  momentum equation to the size of scalar space. \n
