DeformationalHeat Solver

General Information

• Solver Fortran File: DeformationalHeat.f90

• Solver Name: DeformationalHeatSolver

• Required Output Variable(s): W (User Defined)

• Required Input Variable(s): Default Flow Solution (else declared in Flow Solver Name)

• Optional Output Variable(s): None

• Optional Input Variable(s): None

General Description

This solver computes the volumetric heat produced by ice flow deformation.

SIF contents

The output of the solver - the volumetric heat source due to ice deformation - can be directly used within the TemperateIceSolver using the body-force keyword Temp Volume Source (provided your temperature variable is called Temp). Important: Do not use that as a Heat Source for the regular HeatSolve (it would need a specific heat source).

The required keywords in the SIF file for this solver are:

Solver 3
  Equation = DeformationalHeat
  Variable = W
  Variable DOFs = 1

  procedure =  "ElmerIceSolvers" "DeformationalHeatSolver"

  Linear System Solver = direct
  Linear System direct Method = umfpack
  
  Flow Solver Name = String 'Flow Solution'
End

! This would be the correct source for TemperateIceSolver
! with variable name Temp
Body Force 1
   Temp Volume Source = Equals W
End
