SMAP-2D and SMAP-3D are state-of-the-art multi-phase nonlinear finite element analysis programs which can be applied to compute static, consolidation, or dynamic response of dry, saturated, or partially saturated soils and porous rocks.

Both SMAP-2D and SMAP-3D have especially useful features for earthquake analysis since they can continuously perform the static analysis followed by dynamic analysis with appropriate boundary change.


SMAP-2D is the 2-dimensional version which takes account of spherical symmetry, plane strain and axisymmetry configurations. And SMAP-3D is the 3-dimensional Version. The programs can be a useful tool for both research and practicing engineers to study geomechanical response of saturated or partially saturated soils and porous rocks.

Software Requirements

  • Windows 64 Bit Operating System

  • Intel Pentinum 4 or AMD Processor

  • 4 GB Ram with 30 GB Free Space in Drive C

  • SVGA Monitor

Features of SMAP-2D

  • Continuum element allows 2-D plane strain, plane stress and axisymmetric analyses. It can be used for soils, rocks and concrete media. Material yielding and tension-cutoff are considered.

  • Joint element allows separation and sliding along the interface. It can be used for modeling rock joints, fault zones, or structure-soil interfaces.

  • Beam element allows axial, bending and shear deformations. It can be used for rectangular, T-shape or I-shape reinforced concrete or composite beams. Cracking and crushing of concrete and yielding of the reinforcing bar are considered.

  • Truss element allows yielding, buckling and post-buckling. It can be used for rock bolts and anchor bars.

  • Ii contains automatic node renumbering scheme to reduce bandwidth.

  • Updated Lagrangian Formulation is used to model large deformations.

  • It is capable of solving up to 99,990 elements or nodes.

  • It contains several pre-processing programs which can be used to generate nodal coordinates, boundary constraints, element indexes, and applied loads for continuum, beam and truss elements.

Output Data from SMAP-S2

Analysis results are interpreted graphically by post processing programs (PLOT-2D, PLOT-XY and PLOT-3D)

PLOT-2D is used for the following 2-D plots:

  • Finite element mesh with element or node numbers

  • Principal stress distributions

  • Deformed shapes/displacement vectors

  • Truss axial force/stress/strain

  • Beam section force/stress/strain

  • Contours of stresses/strains/motions

PLOT-XY is used for the following time history plots:

  • Stress/strain time histories

  • Displacement/velocity/acceleration time histories

PLOT-3D is used for the following 2-D and 3-D plots:

  • Mesh plots

  • Deformed shapes

  • Beam or truss section forces

  • Isosurface plot for 3-D solid element

  • Principal stress vectors for shell and continuum elements

  • Contours for stresses, strains and displacements for shell and continuum elements
