Altair Multiscale Designer 2025 Release Notes

Highlights

Single Scale Material Support for Forward and Inverse Characterization
Support of a generic user material class

New Features

User-Defined Material Class

The user-defined material class allows the combination of any elastic law with any supported inelastic or damage law. It can be used to define any needed single scale or constituent material behavior, which is not covered be the predefined material classes (polymer, fiber, tow or metal).

Supported combinations are:


Elastic Symmetry	Inelastic Law
Isotropic	Isotropic bilinear brittle damage
	Isotropic 3-piecewise brittle damage
	Orthotropic bilinear brittle damage
	Orthotropic 3-piecewise brittle damage
	Rate independent plasticity
	Rate dependent plasticity
	Hybrid rate independent plasticity and isotropic damage
	Hybrid rate independent plasticity and orthotropic damage
Trans-isotropic	Isotropic bilinear brittle damage
	Isotropic 3-piecewise brittle damage
	Orthotropic bilinear brittle damage
	Orthotropic 3-piecewise brittle damage
Orthotropic	Isotropic bilinear brittle damage
	Isotropic 3-piecewise brittle damage
	Orthotropic bilinear brittle damage
	Orthotropic 3-piecewise brittle damage

Single Scale Material Profile

The Single Scale Material Profile supports forward characterization as well as inverse characterization processes.

All types of material classes (user-defined, polymer, fiber, tow and metal) are supported in the new Single Scale Material Profile.
