Version 1.6 Release Notes

Version 1.6: Date of Release: May 2014

Summary of Major Changes

  • StructureSolver now installs via an InstallShield "setup.exe" file rather than an "msi" file as in previous versions.
  • StructureSolver now requires .NET Framework 4.0, instead of .NET Framework 3.5, which was the minimum requirement for previous versions. By moving to .NET Framework 4.0 we have been able to parallelize computationally-intensive Structural Modeling code. If you are using a multi-core computer very large structural models with many fault points and structural surfaces will remain fully interactive. Note that .NET Framework 4.0 Client Profile (or more a more recent version such as .NET Framework 4.5.1) is standard on updated Window 7 computers and can also be readily installed on Windows XP or Windows Vista.
  • Various improvements were made to the StructureSolver user interface and to the behavior of structural modeling functions - see below.
  • The version of FlexNet Publisher used in StructureSolver was upgraded to the most recent version (11.12.1) and support for licensing using dongles was added.


  • The StructureSolver interface was improved. You can now scroll by clicking and dragging while holding down the Alt Key.
  • The annotation of coordinates in the Locate function has been changed from X: and Y: to Distance: and Depth: for greater clarity.
  • A better method was implemented for automatically determining the horizontal extent of structural models. In previous versions the horizontal model extent for steep faults was too small.
  • The structural modeling logic was changed so that the upthrown-downthrown direction across a fault remains the same if the overall sense of dip of the fault (top-to-bottom) is reversed. This is accomplished by automatically swapping the footwall and hangingwall reference depths when the fault changes dip direction. In previous versions the sense of throw across a fault reversed when the fault changed dip direction. The new modality makes it easier to model create models for steep faults whose sense of dip may not be known (particularly for trishear faults).
  • In previous versions it was not possible to select the top footwall surface in Move Underlying Layers and Move Individual Surface if hanging wall cutoffs were locked. This restriction was removed.
