• Fix a bug involving recomputing the overlap volume between rblocks in 3D.
• Fix a bug when rotating rblocks about a point other than their centroids.
• When in timestep scaling mode, change the rotational equations of motion for rblocks to a simplified version to increase stability of the contact position.
• Add the user_area contact property to all applicable contact models, fixing the contact area.
• Add the reference gap to the softbond model.
• Fix softbond documentation regarding units of kn and ks.
• Add the area method to all applicable contact models, fixing the contact area to the current value.
• Add the BALL TRACTIONS commands to set contact forces consistent with stresses in ball assemblies via Voronoi tessellation.
• Add the RBLOCK TRACTIONS command to set contact forces consistent with stresses in rblock assemblies.
• Add the RBLOCK CONTACT-RESOLUTION INHIBIT-CONTACTS command to inhibit edge and vertex contacts in zero porosity packings of rblocks.
• Fix 2D overlapping polygon bug that could impact contact position and area computations for 2D rblocks with sides collinear.
• Fix 2D EPA bug for rblocks.
