32-bit
and 64-bit versions
- both 32 bit
(Windows XP, Windows Vista) and 64 bit for Vista Buisness
are available
- with 64 bit version it is possible to solve larger problems and usually
faster
- for small problems overall performance increased by factor of 2 -5
- for large problems overall performance increased by factor of 2

Single
phase and two-phase dynamic soil-structure interaction module
- dynamic analysis
of soil-structure interaction in time domain is fully supported
for single and two-phase fully or
partially saturated media
- for
single-phase media Domain Reduction Method (DRM) by J. Bielak
(2001) is implemented, it allows to reduce the size of computational model
- viscous dampers
are developed for both single and two-phase media
·
Nails
with adhesive interfaces
- 2D/3D
analysis of soils strengthened by nails is supported
- nails, treated as beam elements embedded in continuum,
may be supplemented by adhesive interfaces following the philosophy used for
piles
- the ultimate shear stress set up for continuum
materials can be inherited by nails automatically
·
Fixed
anchor zone interfaces
- in 2D/3D modeling of prestressed
anchors one may add a fixed anchor zone with adhesive interface
- this option allows to model pullout test for the anchor
- fixed anchor zone is treated as truss element embedded in the
continuum
- the ultimate shear stress set up for continuum materials
can be inherited by fixed anchor zones automatically
·
New
mapping method of complex geological layers, defined through boreholes, on 3D
meshes
- this option helps to
generate a complex distribution of material layers in the 3D domain discretized by means of continuum elements
- kriging procedure is used with user set up variograms
