GroundedSolver
GroundedMask
(user defined)
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).
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.
The required keywords in the SIF file for this solver are:
To initialise the GroundedMask
variable
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
To get the new value of GroundedMask
. To be executed just after the mesh update.
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
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.
Material 1 ... Min Zs Bottom = Equals bedrock Max Zs Bottom = Real 1.0e6 End
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).
