Release 2026 R1 includes the following analysis enhancements:
Mode Superposition (MSUP) Transient Structural Analysis. You can now use the Load Application feature to apply and scale base excitations or load vectors, generated by an upstream Modal analysis, in a downstream MSUP Transient Structural analysis.
Load Support for Modal Analyses: You can now specify the following loading conditions in a Modal analysis:
These loads do not affect natural frequencies or mode shapes. However, you can use the load vector data from these boundary conditions. Apply and scale them with the Load Application object for downstream Mode Superposition (MSUP) Harmonic Response and/or MSUP Transient Structural analyses.
Apply Commands to Load Vectors Using a Commands (APDL) Object. During Modal or Substructure Generation analyses, you can now use the Commands (APDL) object to apply command snippets to specific load vectors using its new Load Vector Selection Mode property. The options of this property enable you to apply the Commands (APDL) object to all load vectors or a specific load vector of the analysis. Options include All (default) and By Number. This feature requires you to insert the command object under the Environment object of the given analysis.
Multistage Cyclic Symmetry. For stand-alone Static Structural analyses, the application’s multistage cyclic symmetry capability now supports the following boundary condition and loading definitions:
You can now apply Remote Force, Moment, and Remote Displacement boundary conditions within multistage cyclic symmetry setups.
A Rotational Velocity can be specified using a harmonic index value, as defined by the Stage object.
Analysis Settings > Step Controls. A new property, Maximum Iterations Per Substep, has been added to the Step Controls category of the Analysis Settings object. For nonlinear static and transient analyses, this property enables you to specify the maximum number of iterations the solver can perform within each substep of a nonlinear analysis to reach equilibrium.
Analysis Settings > Rotordynamics Controls. The Coriolis Effect property now supports the On, Rotating Reference Frame setting for Harmonic Response, Modal, and Static Structural analyses.
Coupled Field Analyses. When coupling structural and thermoelectric conduction analyses, the application now uses the SOLID225 element for lower order meshes. Previously, it used SOLID226, a higher-order element, but dropped the mid-side nodes. This change ensures more appropriate element selection for the analysis type.
