  2. Hardlock and Nodelock software update.

Version 4.075

  1. In the case were one joint overhangs another, the application of water force on the overhanging joint could have been in the wrong direction. This is an error in the original Hoek and Bray equations.

  2. Improvements to the correlation method for friction and cohesion were made resulting in better correlation.

Version 4.01

  1. The lognormal distribution was not being calculated correctly.
  2. Scaled wedges were not being saved to the data file. If you scaled a wedge, saved the file, read the file back in, you would get the maximum wedge.
  3. Bolts were not being read correctly from the input file. As a result the safety factor would not include the influence of the bolts.

Version 3.06

  1. Fixed a bug with the printing of a wedge view. Sometimes it didn't print.
  2. Added the ability to export image (JPEG,BMP) files. See the File->Export Image File option.

Version 3.05

  1. The Deterministic input dialog no longer resets the data for invalid wedges. This way you can easily play with the values. However, if you exit the dialog, the values will be reset to the last valid wedge you analyzed.
  2. A small left margin was placed in the infoviewer to improve readability.

Version 3.04

  1. Checks for valid statistical parameters for beta and triangular distributions have been added.

  3. 2D histograms are now the default.
  4. Toolbars and the statusbar can now be toggled on/off.
  5. The toolbar font size has been increased making it easier to read.
  6. A display bug that caused improper visualization of the wedge geometry was fixed.
  7. Much improved error messages for improper wedge and tension crack geometry was added.
  8. One of the checks used to determine a valid wedge with a tension crack was removed since it missed some rather important valid cases.
