Virfac® Products Matrix

Virfac® Additive Manufacturing

Virfac® Additive Manufacturing module has the capabilities to compute both the SLM as well as the ALM processes efficiently. It is based on fully transient thermo-mechanical-metallurgical computations, providing the user with highly accurate distortions & residual stresses. This module possesses advanced slicing features wherein the user can generate automatically macro-layers from the CAD geometry. With the help of this module, the user can optimize the build-up orientation, the support configuration and verify the influence of operating conditions on the distortions, plastic strains and residual stresses.

Virfac® Welding Designer

This module is based on the fully transient thermo-mechanical-metallurgical simulation of the welding process, which allows the accurate predictions of distortions, residual stresses and metallurgical transformations. Precise results can be obtained within an industrial time-frame thanks to the Massively Parallel solver capabilities.

Virfac® Welding Scheduler

This module is based on the inherent strain method, or the so-called Local-Global method, using solid elements. The major advantage of this method is its extremely small computational time. The use of Virfac® Welding Scheduler enables the optimization of the welding process by modifying the welding sequence e.g., in order to improve the process without having to perform expensive experimental work.

Virfac® Welding MEGA powered by JWELD

This module is especially suited for the prediction of distortions for very large panels with thin sheets and stiffeners. It uses the JWELD solver from JSOL, a non-linear finite element solver dedicated to shell finite element calculations. Virfac® Welding MEGA interfaces a powerful Inherent Strains database which stores weld models based on experimental or detailed computational data. Virfac® Welding MEGA provides an extremely quick welding modelling prediction tool capable of treating a very large number of welds for sequence optimization.

Virfac® Heat Treatment & Carburizing

This module is dedicated to heat treatment modelling, which allows the user to easily model heating, cooling, annealing and quenching of complex parts. The use of Virfac® Heat Treatment enables the precise calculation of residual distortions and stresses, and the microstructure transformations. It also provides a fast computation modelling methodology for carburizing. The results can be used to compute the influence of the solute on the plastic strains due to the metallurgical transformations.

Virfac® Metallurgy

Virfac® now provides a full metallurgical modelling framework in the material manager. Two levels of metallurgical coupling are available: weak coupling which considers bulk properties of the material to remain unchanged, with phase transformations, and strong coupling where the material properties evolve with changes in the phase fractions. Material properties may also be defined depending on the concentration of solute elements. Metallurgy graphs can now be imported from JMatPro (Sente).

Virfac® Machining

Virfac® Machining DIRECT provides the user with a fast methodology to compute the relaxation of internal residual stresses due to the removal of material by machining. This module is particularly suited for complex & intricate geometries and finds application in aerospace, automotive, and other manufacturing industries where machining dexterity is needed.

Virfac® FSW

Virfac® Welding is based on both a thermo-fluid and a thermo-mechanical formulation. The former is used to model the Friction Stir Welding (FSW) and the effect of materials stirring on the temperature increase and energy generation. The multiphysics and multiscale coupling with the thermo-mechanical analysis leads to accurate and predictive results in terms of residual distortions, residual stresses and microstructure after Friction Stir Welding on large industrial components. It can be also be coupled to Virfac® Welding Scheduler.

Virfac® Crack Propagation Lifetime

Virfac® Crack computes stress intensity factors along the front of three-dimensional cracks and predicts crack propagation under fatigue loading. This module implements the eXtended Finite Element Method (XFEM) for the modelling of cracks in a mesh-independent fashion. The stress intensity factors are computed accurately thanks to dedicated enrichment functions which improve the quality of solution at the crack front. Moreover, Virfac® Crack offers unique algorithms for modelling the propagation of multiple, 3D cracks with no limitation on the crack shape.

Virfac® Multi-Process Workflow

Virfac® is capable of combining several processes efficiently and also managing the exchange of data between each analysis in an easy and transparent manner. Transferring residual distortions and stresses between several processes has never been easier.
