Release Notes – Akselos SPM Platform 2026

Solver

1. Mode Superposition in Harmonic Structural solver: The user can activate this option in order to use a truncated modal basis to perform harmonic analysis. This speeds up calculations but the accuracy depends on the chosen number of modes.

Solver

2. Computation of Work for Plasticity Solver: These fields can now be visualized in addition to the complex-valued pressure. The user can
select them via the Optional Fields menu.

Solver

3. Contact Segmentation for smoother contact results: Users can now choose Contact Segmentation as a contact enforcement method, alongside the pre-existing node-to-surface and surface-to-surface methods. Contact segmentation is the most precise one so far, yielding very smooth pressure fields at the expense of additional computational effort, even in the presence of non-conforming meshes. Currently limited to almost planar contact interfaces and small-sliding contact.

Akselos Modeler and Post-processing

4. Insert custom labels in the graphics window: Users can now insert custom labels directly into the 3D viewport. By accessing the new Measure Notes dialog, you can input specific Node or Element IDs to display solution data (such as Nodal Stress, Displacement, or Temperature). These labels are “pinned” to the specific geometry in the Graphics Window. This allows users to orient the model and capture screenshots with all necessary data visible, removing the need to add text boxes manually in external reporting tools.

5. Update Built-in Solution Fields: The post-processor now automatically computes Tresca stress whenever averaging solutions that include principal stresses. This field is now a default entry in the result selection dropdown menu.

Solver

Enable Reduced Integration for HEX20 in Dynamic Analysis.

Solver

Display Contact Status: The Contact Status field has been updated to render descriptive text strings rather than integer values in the post-processing window. The legend will now display as categories: Inactive, Sliding, Sticking, Stabilization Active.
