In issue #2017 there are several FEM wiki pages listed missing from FC wiki:
FEM_Create
FEM_Material
FEM_Calculation
FEM_DefineNodes
FEM_FixedConstraint
FEM_ForceConstraint
FEM_BearingConstraint
FEM_GearConstraint
FEM_PulleyConstraint
FEM_ShowResult
Posting them in this thread as an FYI and an open invitation for anyone to work on them.
Cheers!
