Chapter 1 Introduction
1.1 Description of the Inventium Suite
The Inventium Suite is an integrated set of software products which are intended for use by
engineers and scientists in support of product development or research activities using finite
element analysis.
The primary toolset included in the Inventium Suite is the PreSys finite element modeling toolset.
The PreSys software includes an integrated preprocessor and post processor as well as
interfaces to major CAD software products. PreSys is a complete CAE software toolset for
applying theory and engineering principles common in areas of mechanical and structural
engineering.The name PreSys is derived from the Greek word for ‘development’ – presis, and the
word ‘precise’. These are both words that resonate with product development engineers, and are
daily concerns for users of finite element software products.
The Virtual Proving Ground (VPG) technology is one finite element tool especially customized and
developed for users of auto industry, which is mainly used in automobile simulation analysis at
system level, including the fatigue life analysis for full vehicles, nonlinear dynamic analysis for full
vehicles, NVH analysis, and crash safety and occupant protection and so on.
The Drop Test Module (DTM) is used to research the product performance in the drop test. These
tests can be used to evaluate the product design and packing material of transportation products,
which will facilitate engineers to reduce the damage to product by using energy absorption
materials and improve the product strength to endure the crash.
The ALE-FSI module facilitates the user to automatically create fluid meshes of various sizes. It
also provides all modeling tools required in fluid-structure interaction simulation. Simulation
results include the deformation, stress, accelerated speed and history. In the drop test, these
