The Altair Partner Alliance expands its composites modeling offering

News International-French

28 Mar 2014

The Altair Partner Alliance (APA) announced that Multiscale Design Systems (MDS) has enabled its software, MDS, on the Altair license manager. MDS focuses on composite materials and structures at multiple spatial and temporal scales. 

MDS delivers a solution that offers a seamless blend of modeling, simulation and testing, while allowing users to quantify uncertainty and optimize composites. Outfitted with methodical model-reduction technology, MDS reduces complex unit cells from hundreds of thousands of finite elements to a manageable number of deformation modes and state variables. It also is equipped with an extensible library of parametric unit cell models that are generated automatically using the built-in CAD and meshing tools. One benefit of MDS is that it has extremely thorough mathematical processes. It is also versatile for users by offering such advanced capabilities as microstructural optimization, multiscale fatigue and multiphysics analyses.

Two versions of MDS are available: MDS-Standard and MDS-Professional. MDS-Standard consists of the Multiscale Design System for Continuum (MDS-C) module. This module resolves microscale fields at a computational cost comparable to that of macromechanical modeling. MDS-Professional includes three modules in addition to MDS-C: Multiscale Stochastic Design System (MDS-UQ), Multiscale Multiphysics Design System (MDS-MP) and Multiscale Fatigue Design System (MDS-FT). The MDS-UQ module is a nonintrusive multiscale solver with stochastic forward and inverse capabilities. MDS-MP couples many physical processes at multiple scales. These can include oxygen and/or moisture diffusion along with reaction and deformation. Finally, MDS-FT uses the two-scale asymptotic homogenization approach for time and reduced order homogenization for space. Both can be effectively applied to any material architecture and any constitutive equations of microphases. The APA will include both versions of the software.

Available for the past 13 years, Altair’s innovative unit-based licensing system allows HyperWorks users customizable access to a growing portfolio of applications, optimizing their return on investment (ROI) by making more than 20 in-house-developed applications available by use of a single pool of recyclable HyperWorks units (HWUs).

Altair also has offered the opportunity for third-party companies to run their own applications under this unit-based system, a collaboration now known as the Altair Partner Alliance. The overall flexibility of these HWUs empowers users via access to the largest, most complete suite of CAE applications available. The ROI increases for users each time a new application is added to the offering, since any of the partner programs can be accessed using the same leased HWUs they are already using to run HyperWorks. This makes more than 50 additional applications available at no incremental cost or long-term commitment.
