ice3 RELEASE NOTES: 11/20/22 RELEASE VERSION 2.15.30
===============================================================

Enhancements/ Additions:
------------------------

* Changed all sprintf calls to snprintf.

Bugs Fixed:
-----------

* 

===============================================================
ice3 RELEASE NOTES: 03/17/20 RELEASE VERSION 2.15.29
===============================================================

Enhancements/ Additions:
------------------------

* Modified Message_Flag (mmsg) usage for values of 0 (no output)
  and -1 (minimal output).

Bugs Fixed:
-----------

* 

===============================================================
ice3 RELEASE NOTES: 02/23/18 RELEASE VERSION 2.15.27
===============================================================

Enhancements/ Additions:
------------------------

* Added additional checks on refinement level differences to
  limit differences between all adjacent elements to one.

* Modified boundary point checking to include a growth rate check
  if cdfr_gap_ic is specified. This is only active when df_ic_min
  is specified or there is only one level of refinement. When
  df_ic_min and cdfr_gap_ic are specified and there are multiple
  levels of refinement then the growth rate check is only active
  on the finest level of refinement.

* Added additional output messages for generation of boundary data.

Bugs Fixed:
-----------

* Corrected a fatal memory issue if any refinement levels are removed.

* Corrected an issue related to checking elements on refinement
  level interfaces. This can occur with sources that extend to
  the domain boundaries.

ice3 RELEASE NOTES: 02/23/17 RELEASE VERSION 2.11.17
===============================================================

Enhancements/ Additions:
------------------------

* Moved ice3_split_data routines to UG3 library (removes ANBL3 dependency on
  ICE3 library).

* Revised interior core mesh (ICE) algorithm. These changes
  improve refinement near outer boundaries. Particularly those
  with large regions where the surface is flat and the surface
  normal is in only the x, y, or z coordinate direction. 

* Changes for compatibility with 64-bit integers.

Bugs Fixed:
-----------

*

===============================================================
ice3 RELEASE NOTES: 12/06/16 RELEASE VERSION 2.9.15
===============================================================

Enhancements/ Additions:
------------------------

* Added capability to set and save data for hex elements that
  have split quad faces (adjacent element has 2:1 refined spacing).

Bugs Fixed:
-----------

*

===============================================================
ice3 RELEASE NOTES: 10/16/16 RELEASE VERSION 2.6.6
===============================================================

Enhancements/ Additions:
------------------------

* Complete revision of interior core mesh (ICE) overall approach.
  If this option (-ice) is specified then the new version will
  generate a Cartesian core with isotropically varying hex size
  dependent upon a background mesh. AFLR3 will automatically
  generate the background mesh if one is not input. The resulting
  mesh has a minimal region of truly unstructured mesh adjacent
  to each surface.

Bugs Fixed:
-----------

  file.

Bugs Fixed:
-----------
