  • Release 2022-2 (8 June 2022)
    • Installer includes the software publisher’s certificate
    • Added a button to the Coordinates window that reverses the order of vertices.  This is handy if you digitized a boundary in the opposite direction and want to reverse it.
  • Release 2022-1 (11 May 2022)
    • Eliminated delays that can sporadically occur when selecting Solve.
    • Fixed bug that could cause a crash when contouring a model with zero head difference and the contour increment set to zero.
    • This release was not announced, as the installer lacked the software publisher’s certificate.
  • Release 2021-2 (27 Oct 2021)
    • The Surfer grid file export feature under the Plot File menu has been improved so the file imports as a text grid import file (*.grd) to Surfer without any modification needed.
    • In cases where the head drops below the base of an unconfined domain, the stored grid value is set to the base elevation.  This improves the appearance of exported grids when used in Surfer or other surface visualization tools.
    • Increased the marker size in plots of calibration target heads vs. modeled heads to improve plot appearance.
    • Fixed bug in automated run output of gridded data in transient models.
    • Fixed bug in multi-segment line pathlines, so pathlines starting from all segments of the polyline are drawn.
    • Fixed bug in Analysis/Check Boundary Condition at Latest Iteration, which had prevented display of this feature in the prior release.
