Modelling Features
- Error
and convergence reports provide simple and clear
interpretation of results
- Powerful
use of problem symmetry to reduce computer time
and improve accuracy
- Simple
zoning of problems to improve accuracy, reduce
computer time and define regions of varying properties
- Definition
of boundary conditions in global and local co-ordinate
systems
- Combined
use of discontinuous and continuous elements
makes mesh refinement and grading in areas of
interest very simple, keeping model size to a
minimum
- Body
loads including point, line sources and forces,
volume sources, rotational and acceleration loads
Element Library
- Complete
range of elements including both discontinuous
and continuous elements
- Hierarchical
element types allow model refinement without
change of mesh
- For
three dimensional problems, quadrilaterals and
triangles
- For
two dimensional and axisymmetric problems, lines
- Tube
elements for modelling cylindrical voids in 3D
thermal problems
- All elements have high
order shape functions for accurate model representation
Full User Control
- Free
format input data
- Stop
and restart
Contact Simulation
- Accurate
analysis of surface gap/contact problems
- Analysis
of single and multiple contact surfaces
- General
2D axisymmetric and 3D geometries
- Coupled
stress and thermal analysis
- Contact
with external rigid surfaces
- Interference
fit
Comprehensive loading features are
available and the user can simply specify initial
gaps or overlaps (interference fit) of the contact
surfaces. The automatic contact algorithm takes
care of the rest.
Contact models can also be coupled with thermal models to include both
stress and thermal effects.

Contact Simulation
- Comprehensive
checking of data and of computer resources
required ensures that no analysis runs
are wasted
- Local
error guides to give clear indication
of solution accuracy
- Evaluation
of total force and thermal balance
- Combination
of thermal and stress analysis to undertake
a thermal stress analysis
- Efficient
and economical solution at as many user-specified “internal
points” as required
- Step-by-step
analysis option allows re-analysis to
be carried out after minor changes without
re-calculation of matrices
Zoning or Substructuring
A model can be split into any number of zones or substructures
to represent different components or materials or to simplify
the model.
