Improvement to spatial search efficiency over objects with zero volume:
geometry-distance and geometry-count range elements and the geom.dist.closest FISH intrinsic.zone initialize-stresses, structural element links to zones, interface contact searches, building-blocks validation, and more. FLAC3D The interface logic has been updated - in general to make it easier to deal with models with many interfaces:
- A name token after the zone.interface keywords is now optional. If not present the command applies to all interfaces.
- If a name is not explicitly assigned when using the create command it will be created automatically. It can be given as a new name keyword as part of the interface creation parameters.
- The zone.interface.node.history command requires an interface name if the node is selected by id keyword. The name can be given as a suffix along with the id keyword. If selected by position and no name keyword is given the nearest node on all interfaces is selected.
- Interfaces, interface elements, and interface nodes now have group command and FISH function support. They participate in the group heirarchy. Interface elements also check the groups of zone faces (and therefore zones) they are connected to in the heirarchy.
- Interfaces have their interface names assigned as group names automatically on creation. This means that interfaces, interface nodes, and interface elements can be selected by the group range element using the interface name.
- Pore pressure is available as an interface contour option.
- The interface normal state plot will now include tensile failure and shear bond failure indicators.
- Added an interface.node.near FISH function. If the interface pointer is null it will search all interfaces.
- Added an interface.node.state FISH function. Returns the interface node state encoded as bits in an integer.
- Added color by interface group, element group, and node group to the interface plot item.
- Interface element creation uses a break angle to determine if nodes should be shared across faces. The default is 30 degrees and can be set with the break-angle keyword. This should make it much easier to create interfaces around corners that behave properly.
- Interface element creation can force separate nodes across regions by using the break-slot keyword. If the group name changes in that slot (in zones or zone faces) then nodes will not be shared across the elements. This can be used to force multiple nodes along boundaries of regions on a surface (useful if there is a T junction).
New features and improvements:
side attribute is now available on all appropriate structural element plot items, not just for liners. tensile-plastic-strain failure to cable elements. Also added tensile failure state to pile and cable state plots. geometry xxxx set "bob" orientation keyword to the dfn range element. list.append, list.extend, list.insert, list.insert.list, and list.prepend. Also tried to clarify the list type documentation. geom.set.poly.closest FISH intrinsic - more efficient than the geom.set.closest intrinsic if only polygons are of interest. (x,y) used as a range when y < x. Instead of swapping the values, it treats it as a null range. This means that on the right it will return a null string or empty list. On the left it can be used to insert one or more values without overwriting any existing elements. Bug Fixes:

it.zone.near python function. zone.field.component FISH function. New features and improvements:
zone densify command:segments and result of the maximum-length calculation have been constrained to even powers of two (1,2,4,8,...). Note technically this is a backwards compatibility break.edge-limit that simply checks if any zone edge is greater than the limit and if so applies the specified division in segments -- as opposed to maximum-length that if done without a repeat keyword will calculate the number of divisions.aspect-ratio keyword that applies densification in the direction of maximum aspect ratio if above the limit specified. This currently only works on hexahedral zones.group-begin and group-end keywords. This will also occur when using struct cable import (for example) by performing a scan of the new elements created.Bug Fixes:
3DEC Fixed bug creating liners on excavated (not deleted) tunnel surfaces.
