==== General Description ==== | ==== General Description ==== |
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 m 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. |
