GridDataReader Solver

General Information

  • Solver Fortran File: GridDataReader.f90 (under elmerice/netcdf2-tree)
  • Solver Name: GridDataReader
  • Required Output Variable(s): None
  • Required Input Variable(s): None
  • Optional Output Variable(s): all from NetCDF file interpolated variables
  • Optional Input Variable(s): None

Compilation

Update 37f46d0 under elmerice branch
Now you can automatically build, test & compile the solver with cmake.
KeyWorkds:

cmake
   -DWITH_GridDataReader:BOOL=TRUE \
   -DNetCDF_INCLUDE_DIR=PATH_TO_INCLUDE \
   -DNetCDF_LIBRARY=PATH_TO_libnetcdf.so \
   -DNetCDFF_LIBRARY=PATH_TO_libnetcdff.so \

Old Version
This solver is not part of the standard Elmer/Ice installation and has to be compiled manually. There is an example compilation call in the directory. Naturally, the system needs to have a compatible NetCDF library installed. In particular, the Fortran compiler with which the NetCDF library has been compiled has to be the same Elmer and Elmer/Ice has been compiled with (module compatibility)

General Information

This auxiliary solver enables to read in variables from a NetCDF file and interpolates the values to the mesh as variables of the same name. The interpolation is done by using the Finite Element test functions.

Known Bugs

None, so far.

  Interpolation Bias = Real 0.0 
  Interpolation Multiplier = Real 1.0 

  Is Time Counter = Logical True

  Variable 1 = annualtemp
  Variable 2 = julytemp
  Variable 3 = preciptation
  Variable 4 = ablation
  
  Enable Scaling = Logical True ! Scales the Elmer grid to match the NetCDF grid - dangerous
End

Test

Located under [ELMER_TRUNK]/elmerice/Tests/GridDataReader
You can test with

ctest -L GridDataReader
or 
ctest -L netcdf

Example

The directory [ELMER_TRUNK]/elmerice/netcdf2 contains the example above, that should work with the NetCDF file provided by the searise group.
