Release 2026 R1 includes the following result enhancements:
Result Data Caching. For Modal and MSUP Harmonic Response analyses, when the On Demand Expansion Option property (Analysis Settings > Options) is set to Yes, all result types now include a new property: Save Auxiliary Results. When enabled, this property automatically caches result data in memory. This caching significantly improves result retrieval and display performance when switching between objects. The performance improvement is maintained even after you close and reopen a solved analysis.
Line Chart. For LS-DYNA analyses, new features and capabilities are available for the Line Chart feature, including:
Charting X Axis Source Data. The new X Axis property enables you to choose a dataset to plot on the x-axis and the remaining datasets are reconstructed to map to this newly specified axis.
Updating the Chart Source Data. A new Update option is now available for when you modify source objects. When selected, the application deletes the datasets of the source object(s) and re-imports the revised data, ensuring the chart reflects the most current information.
New Source Data Types: Line charts now support the loading conditions Acceleration, Force, and Pressure as source data objects.
Editing Labels. You can now directly edit the content of a chart label.
A new Chart tab is now available in the Chart Options window. This tab enables you to customize the chart's display using the following options:
Title: Enter a title to display at the top of the chart.
Font Size: Select the font size for the chart title.
Legend: Toggle the legend on or off.
Position: Define the position of the legend. By default, this property is set to Program Controlled, which positions the legend in the most ideal location based on the data presented in the chart.
Many of these new features offer associated APIs. See the Working with Line Charts section of the Mechanical Scripting Guide for more information.
Calculating Midside Node Results. For the supported solid element types, use the new Options dialog preference, Compute Midside Node Values Based on Averaged Corners (Options > Results > Default), to specify how the application calculates midside node results. For averaged results, set the preference to:
Yes (default) to first calculate the averaged corner node values and then the midside node result using the calculated averaged corner node values.
No to calculate midside node values using unaveraged corner node values.
Moment Reaction Probe. There is a new preference, Moment Probe Summation Point Offset By Displacements (Options > Results), which affects the calculation of the moment arm of a Moment Reaction probe. With this preference enabled, the application moves the Summation point for the probe to match the closest deformed node. Options include Yes and No (default).
Far-field Results on Adapted Meshes. You can now compute Far-field results in Harmonic Acoustics analyses when using an adapted mesh generated through the Mesh Morphing feature.
Displaying Only the Body with Maximum Result Value. A new context menu option, Show Body With Max Result, is now available for all evaluated result objects. When selected, the application automatically displays only the body that includes the maximum value, as determined by the location of the Maximum Occurs On property value, for the specified result.
