PreSys
PreSys
is an engineering simulation solution for the development
of finite element analysis models. It offers an intuitive
user interface with many streamlined functions, allowing
fewer operation steps with a minimum amount of data
entry along the way. Using PreSys, the user can analyze
product designs, view simulation results and analyze/predict
how the product will perform in a given circumstance.
Building on an efficient framework, PreSys is the price/performance
leader. Through the "zero text editing" environment,
all of the capabilities within LS-DYNA,
NASTRAN and RADIOSS
are easily accessible through the user interface.
Results visualization is easy with PreSys. The software
automatically detects the type of model being viewed
and makes the appropriate files available for viewing.
Large system models of structures are a specialty. FE
models of large complex structures can quickly be generated
by using PreSys' Topology Automesher. The Topology Automesher
provides an intelligent automeshing system which reduces
modeling and assembly time drastically.
All
major FE softwares are supported in PreSys. Interfaces
such as NASTRAN, LS-DYNA and RADIOSS are 100% "zero-text
editing" environments which can easily convert
between one another.
Automated
Tetra Meshing is easily performed using PreSys'
meshing tools.

VPG
VPG is a set of plug-ins for PreSys, which allow the
user to quickly & efficiently create finite element
models & define the models for mechanical system
analyses. It can be used to simulate common automotive
safety test conditions, drop tests, fluid-structure
interaction & structural analysis accurately.
Drop Test
The Drop Test plug-in enables engineers to simulate
designs undergoing the abuse of everyday use & the
extremes of the product lifetime.
Fluid-Structure
The FSI application allows the user to create advanced
fluid-structure interaction simulations, automatically
creating ALE mesh zones & explosive pressure sources.
The user can set-up LS-DYNA® models with multiple
fluid zones & variable charge shapes using a simple
parametric model definition.
Safety
The Safety plug-in allows the user to set-up LS-DYNA®
safety simulations, including FMVSS & ECE vehicle
safety test simulations. Occupant modeling is supported
to interactively position finite element dummy models
& add seatbelts.
Structure
With the Structure plug-in, the user can analyze tire
models, suspension models & road surfaces. The plug-in
offers a dynamic non-linear analysis approach, using
real-time boundary conditions consistent with common
test environments.
