LimitState:FORM Release History

Current version

v3.0.4 [3940]

Major Update

11th April 2017

Enhancements

Added functionality

  • Added a materials library containing a range of generic representations of additive and structural materials. These can be used in the project and / or copied and modified [ref 433]
  • Added a tool to allow users to conduct a frequency analysis on the structure [ref 804] [ref 865]
  • Added the ability to calculate and display elastic (frame) bending stresses for the optimized solution [ref 848] [ref 938]
  • Added an "Advanced" support type. This feature allows users to set limiting support forces, align supports to a local coordinate system and / or provide support to bodies from a point not necessarily on the body itself [ref 902] [ref 907]
  • Added the ability to undertake Euler buckling checks on the members as part of a geometry optimization [ref 954]
  • Added 'advanced support' force and moment data to CSV output [ref 1032]

Improved interface / documentation

  • Improved the usability of the "Edit" functions by providing the user with an enhanced understanding of the modifications made prior to Complete. For example, objects are now color-coded according to the alterations that are being attempted [ref 386] [ref 915] [ref 918]
  • Allow point loads and supports to be applied to curves and points lying on the surface of a solid [ref 589]
  • Compacted the layout of the ribbon bar (improves user experience on lower resolutoion displays and streamlines workflow) [ref 929]
  • Provide an option to only display buckling modes with positive values [ref 934]
  • Improvements to solve dialog, including addition of ability to specify load cases as active or inactive [ref 935]
  • Extended range and depth of descriptive text for items in the user interface [ref 939]
  • Updated the Materials dialog to make the process of definition and assignment more intuitive [ref 945]
  • Updated and unified text descriptions of solution components (members, joints etc.) in order to aid user familiarity and understanding [ref 985]
  • Added new sections and improved descriptions in the User Manual [ref 1012]
  • Updated User Guide to include additional information and make Quick Start and Tutorials easier to follow [ref 1041]

Enhanced reporting

  • Display solver output in tabulated form [ref 762] [ref 925]
  • Added information to the filter pane in order to aid the user in deciding a suitable value to use. Additionally, highlight the members to be deleted such that it is clearer to the user what will occure on complete [ref 792] [ref 873]
  • Added a variety of useful data on the generated solution to the Optimization (left) panel [ref 853]
  • Report the estimated violation of nodes outside the design domain when the "Fit joints" option is selected [ref 956]
  • Improve reporting of numerical issues encountered when a structure geometry is inherently unstable and a stability check is carried out [ref 963]

Other improvements

  • Add rigid body mass to GSA output for dynamic analysis [ref 885]
  • Added the ability to pass generated solutions (along with loading and boundary conditions) to ANSYS Workbench. This allows users to conduct further FEA analyses and includes the capacity to modify the geometry in LimitState:FORM and update on the fly in ANSYS [ref 900] [ref 962]
  • Automatically set rigid bodies to have the same material properties as the design domain [ref 904]
  • Implement Spectra SymGEigsSolver in order to increase (>10x) the speed of linear elastic analysis calculations [ref 908]
  • Aded more worked tutorial files to the User Manual and website [ref 1018] [ref 1020]

Bugfixes

  • Update the stability calculations when switching between load cases in the viewer [ref 837]
  • Suppress the hiding of built-in SpaceClaim panels [ref 842]

  • Preserve minimum member area for both sections when splitting [ref 857]
  • Updated warning regarding unapplied modifications made using the validation tools [ref 875]
  • Various fixes to ensure that data is not passed between the output windows in open files [ref 888] [ref 897]
  • Various fixes to GSA export functionality [ref 893]
  • Allow mirror planes to be applied to design domain solids that exist within components [ref 903]
  • Issue a prompt to install ANSYS if an attempt to launch it is made from within LimitState:FORM, but the machine does not have it available [ref 936]
  • Output standard section types to GSA file when in 'General' mode [ref 964]
  • Updated material descriptions to use "Tensile Strength" instead of "Yield Stress" [ref 978]
  • Implemented a more efficient method of animating deflected rigid bodies (fixes a bug that could sometimes cause a "direction is zero" message to appear) [ref 1030]
  • Updated descriptive text for advanced support force limits to make it clearer how they are used [ref 1038]
  • Fixed a bug that could prevent files from being opened using the "drag and drop" method [ref 1042]
