 ==== General Description ====
-This solver compute the vertically integrated horizontal velocity, either on the bedrock surface or or the upper surface.
+This solver compute the mean vertically integrated horizontal velocities, either on the bedrock surface or on the upper surface. If the keyword ''Compute Flux'' is set to ''True'', the horizontal fluxes are computed else the mean horizontal velocities are computed (default).
 ==== SIF contents ====
-In the SIF example below, the normal stress on a boundary is inferred from the 3rd component of the Stokes residual.

 ==== Examples ====
+An example using the ''IntegratedVelocity'' Solver can be found in ''[ELMER_TRUNK]/elmerice/Tests/IntegratedVelocity''.
-In this {{:solvers:test_force_to_stress.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.
