Altair Multiscale Designer™

Material Model Development Framework

What is Multiscale Designer?

Multiscale material modeling is a powerful method to gain insights into advanced material behavior. Especially for composite materials, multiscale is an accepted, essential approach for predicting material properties accurately and efficiently for use in structural simulations.

Fully integrated with Altair's simulation products, Multiscale Designer is a comprehensive framework for the development of highly predictive and computationally efficient material models for all material behaviors ranging from homogeneous isotropic to heterogeneous anisotropic. Multiscale Designer reduces the time and cost associated with the development of highly predictive material models with minimal experimental data requirements.

Multiscale Designer's material models can be used with standard industry solvers to improve design optimization of advanced material designs through multiscale structural simulations. Well-defined methodologies are offered for developing material models including continuous fiber-reinforced materials, unidirectional and woven products, and injection molding materials, short and long fiber-reinforced products. In addition, a methodology for modeling lattice structures is also available.

Multiscale Designer's material models can be used in implicit and explicit analyses within the most popular commercially available solvers, and support hardware parallelization on different platforms.

Why Multiscale Designer?

Improve the Composite Design Process

By performing the right tests for material characterization, the multiscale approach improves the accuracy of simulations significantly. With the reduced need for physical testing, better designs are generated in less time.

Perform More Reliable Composite Simulations

Utilize our well-established methodology for performing reliable composites simulations. Once a multiscale material model has been developed, its application in simulations is straightforward and requires no specific multiscale expertise.

Get Accurate and Complete Material Data for Simulation

Obtain accurate multiscale material models through a well-defined process. The material models can be used for implicit and explicit finite element analysis with Altair OptiStruct™ and Altair Radioss™, along with well-known third-party solvers.

Key Features

Single and Multiscale Material Models

Our intuitive three step process allows you to develop highly predictive, computationally efficient single or multiscale material models. With minimal experimental data, you can create materials ranging from brittle and/or ductile homogeneous isotropic, to heterogeneous anisotropic.
