Altair Multiscale Designer 2025.1 Release Notes

One of the major targets of Release 2025.1 is adding all relevant features, which were supported in version 2024.0 and were not yet supported in the new Multiscale Designer GUI. These features are:

Review of the full elastic homogenization results

Within the linear forward homogenization a third tab is added, which shows the full results in tension in compression of homogenization, as it was available in version 2024.0.

Support of core material class

Foam and Honeycomb unitcells are supported as core material classes.

Diffusivity and Thermal conductivity

Homogenization supports, as in version 2024.0, diffusivity and thermal conductivity.

General inverse characterization

A general inverse characterization procedure, which allows the definition of any parameter of the multiscale material model as design variable, to fit any elastic and inelastic test result is added. That method enables the user to develop their own inverse characterization approach, fitting to the characteristics of the material of interest.

• In some cases, the Structural Simulation Tasks were not visible in the navigation panel. This is now fixed.
• Update of optimized material parameters in the database did not handle the internal constraints correctly.
