TemperateIceSolver Model Input Error

[denis.cohen]

Hello,

Trying to run the TemperateIceSolver I get the following error:

Code: Select all

The file TemperateIceSolver.f90 compiled fine with elmerf90 (obtained from trunk version 5705).

Here is excerpt from sif file (which I copied from the wiki page) :

Code: Select all

Solver 3
!------------------------------------------
! Heat equation

  Exec Solver = "Always"
  Equation = String "Homologous Temperature Equation"
  Procedure =  File "/home/dcohen/apps/elmer/applications/bin/TemperateIce.exe" "TemperateIceSolver"

  Before Linsolve = "EliminateDirichlet" "EliminateDirichlet"
  Variable = String "Temp"
  Variable DOFs = 1

  Stabilize = Logical True
  Bubbles = Logical True
  Optimize Bandwidth = True
  Steady State Convergence Tolerance = 1.0e-05

  Linear System Solver = "Iterative"
  Linear System Iterative Method = "BiCGStab"
  Linear System Max Iterations = 500
  Linear System Convergence Tolerance = 1.0E-07
  Linear System Preconditioning = "ILU0"
  Linear System Abort Not Converged = True
  Linear System Residual Output = 1

Any help appreciated.
Thanks

Hi Denis,

The problem is in the Material part of the sif file.

Seems that "temp heat capacity" is not well defined (may be it is just a Real missing before the value ?

Hello,
here is my material section (copied from TemperateIceSolver on the wiki page):

Code: Select all

Material 1

  Density = Real 917.

  !-----------------------------------------------------------
  ! the heat capacity as a MATC function of temperature itself
  !-----------------------------------------------------------
  !Heat Capacity = Real 2100.0
  Temp Heat Capacity = Variable Temp
     !Real MATC "capacity(tx)*1.0E06*(31556926.0)"
     Real MATC "capacity(tx)"

  !--------------------------------------------------------------
  ! the heat conductivity as a MATC function of temperature itself
  !--------------------------------------------------------------
  !Heat Conductivity = Real 2.075
  Temp Heat Conductivity = Variable Temp
     Real MATC "conductivity(tx)"

  !-------------------------------------------------
  ! Upper limit - pressure melting point
  !  as a MATC function of the pressure (what else?)
  !-------------------------------------------------
  Temp Upper Limit = Variable Depth
     Real MATC "pressuremeltingpoint2(tx)"

  !--------------------------------
  ! lower limit (to be save) as 0 K
  !--------------------------------
  Temp Lower Limit = Real 0.0

This is the same as the wiki page so I don't get it.

Thanks for any help

Hi Denis

I think that you can't have comment within a continuous expression. The "Variable ..." prepares the parser to read the type of dependency and you give a comment...

Hello Peter,

Indeed, comments not allowed inside continuous expression
Thanks
