GeonX develops robust and powerful software packages to support
manufacturing engineers in their daily design duties. From the design
offi ce to the factory, VIRFAC (VIRtual FACtory), provides an accurate,
powerful and industrial platform of virtual manufacturing. Making of vir-
tual manufacturing a reality is the mission of geonX.
After 10 years of development by engineers from the research center
Cenaero, specialized in advanced computational methods, geonX is inte-
grating this approach in today’s product development environment by
marketing its new generation manufacturing software VIRFAC, powered
by MORFEO (Manufacturing ORiented Finite Element tool). This innova-
tive software is the new reference in unifi ed simulation for applications
ranging from transformation and assembly processes to in-service struc-
tural response.
VIRFAC is built with the most modern object-oriented programming
technologies and has been particularly designed to handle large and
complex mechanical components for realistic industrial environments

VIRFAC FEATURES
VIRFAC/crack is the fi rst commercial software able to perform fully
automated industrial three-dimensional fatigue crack propagation
in complex assemblies with the eXtended Finite Element Method
(XFEM). Cracks are easily introduced in complex models via levelset
functions. Accurate stress intensity factors are readily computed and
used to assess the structural integrity of the par ts. Adequate level-set
update functions and propagation laws are then used to freely prop-
agate cracks in the mesh, with automatic handling of the topological
changes. Seldom manual interventions are needed with VIRFAC/crack,
thereby helping engineers make crucial decisions during design phases
or during investigation of critical in-service failures. The crack module
also plays a key role in the analysis of manufacturing defects.
An original algorithmic strategy makes VIRFAC/machining effi cient
for the simulation of multi-pass machining simulations. Relaxation of
stresses generated during upstream processes is often the most criti-
cal source of distortion during the machining process. In order to pre-
dict them accurately, it is crucial to take the whole sequence of passes
into account. Therefore, the level-set (signed distance) is used to rep-
resent each path so that the workpiece can be meshed separately to of
the different cutting surfaces. This offers a strong advantage over the
classical Finite Element approach which would require heavy remesh-
ing operations after each machining step. This method guarantees that
cutting paths are defi ned in an initial undeformed confi guration while a
deformed workpiece is considered for the next machining pass.
VIRFAC/FSW allows for the Friction Stir Welding (FSW) process to be
modelled at several scales. A local thermo-fl uid model and a com-
ponent scale thermo-mechanical model are coupled. The local scale
thermo-fl uid FE model is available to predict temperature cycles and
strain-rates around a FSW tool. Both, conventional and bobbin tools
can be modelled. Steady state and transient thermo-fl uid models are
available, thus allowing the fl ow and temperature fi elds around tools
with complex geometry to easily be modelled. The output data from the
thermo-fl uid model may be used as input data to metallurgy models to
predict for example the hardness distribution across a weld. The vis-
cous dissipation calculated in the thermo-fl uid calculation can be used
as a heat source in a global thermo-mechanical simulation to deter-
mine residual stresses in a FSW component.
VIRFAC/welding proposes a transient numerical model for a variety
of welding processes. The modeling of the thermomechanical problem
allows the user to accurately predict the level of residual stresses and
distortions at the end of the process. The use of VIRFAC/welding ena-
bles the optimization of the welding process by modifying the clamp-
ing system and/or the welding sequence in order to improve the design
without having to perform expensive experimental works. Accurate
results within a feasible time-frame can be obtained due to VIRFAC’s
parallel solver capabilities. Welding trajectories can be defi ned directly
from CAD geometry allowing easy defi nition of complex and multiple
welding paths. These welding features are effortlessly defi ned using
VIRFAC’s user-friendly graphical user interface.
