-For a given boundary, this solver computes the nodal stress equivalent to a given nodal force. Force here means the resultant of a variable, named stress, which is of the same units than the force but per m2 in 3D or in 2D. This can be used also to infer the flux from the knowledge of a debit or to infer a tangential stress from the knowledge of a tangential force. +For a given boundary, this solver computes the nodal stress equivalent to a given nodal force. Force here means the result of a variable, named stress, which is of the same units than the force but per unit-area in 3D or unit-length in 2D. This can be used also to infer the flux from the value of a debit or to infer a tangential stress from the value of a tangential force.

-In this {{:solvers:test_forcetostress.tar.gz|example}}, a pressure applied on a boundary is first integrated to get  nodal force using the [[solvers:gethydrostaticloads|GetHydrostaticLoad Solver]], and then the pressure is recovered using the ForceToStress Solver.  +In the example found in ''[ELMER_TRUNK]/elmerice/Tests/ForceToStress'', a pressure applied on a boundary is first integrated to get  nodal force using the [[solvers:gethydrostaticloads|GetHydrostaticLoad Solver]], and then the pressure is recovered using the ''ForceToStress'' Solver.
