 ==== General Informations ====
   * **Solver Fortran File:** ''GroundedSolver.f90''
-  * **Solver Name:** ''GroundedSolver'' and ''GroundedSolverInit''
+  * **Solver Name:** ''GroundedSolver''
   * **Required Output Variable(s):** ''GroundedMask'' (user defined)
-  * **Required Input Variable(s):** Read ''Min ZsBottom''
+  * **Required Input Variable(s):** Need to read the bedrock, which can be either a variable or a material parameter (default is the material parameter 'Min Zs Bottom')
   * **Optional Output Variable(s):** None
   * **Optional Input Variable(s):** None
+==== Versions ====
+The solver ''GroundedSolverInit'' has been suppressed (version 7078). Instead, the solver ''GroundedSolver'' should be executed twice (one before the simulation and one at each time step).
 ==== General Description ====
-The aim of this solver is compute a mask to qualify which part of the bed is grounded, which one is floating and which one belongs to the grounding line. The ''GroundedMask'' value is +1 where grounded, -1 where floating and 0 on the grounding line (also grounded).
+The aim of these solvers is to compute a mask to qualify which part of the bed is grounded, which one is floating and which one belongs to the grounding line. The ''GroundedMask'' value is +1 where grounded, -1 where floating and 0 on the grounding line.
 ==== SIF contents ====
 The required keywords in the SIF file for this solver are:
+To initialise the ''GroundedMask'' variable
 <code>
+Solver 1
+  Exec Solver = Before All
+  Equation = "GroundedMask"
+  Variable = "GroundedMask"
+  Variable DOFs = 1
+  Procedure = "ElmerIceSolvers" "GroundedSolver"
+  ! Give a tolerance for the bedrock
+  Toler = Real 1.0e-03
+  ! DEFAULT: Bedrock is read in the material parameter "Min Zs Bottom"
+  !! OR Use this keyword if the bedrock is given as a variable
+  ! Bedrock Variable = String "bedrock"
+  !! OR use this keyword if the bedrock is given as a material parameter
+  ! Bedrock Material = String "Min Zb"
+End
+</code>
+To get the new value of ''GroundedMask''. To be executed just after the mesh update.
+<code>
+Solver 15
+  Equation = "GroundedMask"
+  Variable = "GroundedMask"
+  Variable DOFs = 1
+  Procedure = "ElmerIceSolvers" "GroundedSolver"
+  Toler = Real 1.0e-3
+  ! DEFAULT: Bedrock is read in the material parameter "Min Zs Bottom"
+  !! OR Use this keyword if the bedrock is given as a variable
+  ! Bedrock Variable = String "bedrock"
+  !! OR use this keyword if the bedrock is given as a material parameter
+  ! Bedrock Material = String "Min Zb"
+End
+</code>
+The bedrock elevation is read through the keyword ''Min Zs Bottom'' which is in the ''Material'' section. Here ''bedrock'' is a variable which contains the bedrock elevation.
+<code>
+Material 1
+  ...
+  Min Zs Bottom = Equals bedrock
+  Max Zs Bottom = Real 1.0e6
+End
 </code>

-Download here an example.
+An example testing the Grounded solver can be found in ''[ELMER_TRUNK]/elmerice/Tests/Grounded''.  See also GL_MISMIP and Contact (also in the Tests directory).
