SNBV Package PUBLIC MODIFICATIONS LIST
========================================================================

---------------------------
snbvPkg | PFC2D/3D | Date/Description
9.5     | 9.7.48   | 07/09/26

  Add ability to create and test PFC2D SNBV material (see SNBV Support memo).

  Modify 3D functionality as follows.
    (1) The particle size distribution curve is a cumulative distribution of
        mass according to particle size. In the previous package and Potyondy
        et al. (2025), it was a cumulative distribution of particle counts.
    (2) Specimens are loaded four times faster than before, this is still
        approximately quasistatic.
    (3) Platens are now disks; they used to be infinite planes.
    (4) Radial stress and radial strain are measured as average from three
        overlapping measurement spheres along specimen axis. Radial stress
        used to be measured from a single measurement sphere at specimen
        center. Radial strain used to be measured from ring of bonded blocks
        at specimen middle.
    (5) Confined tests behave as follows. Apply and maintain stress boundary
        condition on sides. Apply stress to axial boundaries by activating
        platen wall servoes, then deactivate the servoes and specify platen
        velocities for subsequent test. Confined tests used to maintain stress
        boundary conditions on entire specimen boundary.

---------------------------
snbvPkg | PFC3D  | Date/Description
9.4   | 9.00.180 | 06/13/25

  Update snbvMemo to note that the name of the grain-strength parameter {with
  FISH name UCSrat} is incorrect in Table 1 of the Potyondy et al. (2025)
  journal paper. The correct name is {UCS to tensile strength ratio (sigma_c /
  sigma_T)} with capital T instead of lowercase T.

---------------------------
snbvPkg | PFC3D  | Date/Description
9.3   | 9.00.180 | 06/10/25

  Provide link address to snbvPkg on Itasca website. Update snbvPkgMemo.

---------------------------
snbvPkg | PFC3D | Date/Description
9.2  | 9.00.179 | 04/01/25

  Confirm that package works with PFC3D 9.00.179, and minor updates to snbvPkg
  memo.

---------------------------
snbvPkg | PFC3D | Date/Description
9.1  | 9.00.177 | 02/24/25

  Release SNBV package to the world.
