Class
    solidTractionFreeFvPatchVectorField

Description
    Traction free boundary condition for solid foam solvers.
    Suitable for for total strain or incremental strain total or
    updated Lagrangian approaches.
    Contains thermal-elastic, plastic, non-linear terms if required.
    And non-orthogonal correction.
