Altair SimSolid 2019.4.0.59

Highlights

Highlights of this release include new linear load case superposition, new import force and import remote force from CSV file function, new result datumsets and new partial dynamic response. New results include dynamic reaction forces, strain energy densityand RMS von mises stress in Random response. In addition, both solution settings and connection/contact workflows have been refactored to make them more intuitive and efficient.

New Features

Load case superposition – Linear load case superposition is now supported for structural and thermal analyses. Superpositionwork benches may be createdafter one or more structural or thermalanalysis has beencreated and solved. Load cases can be combined and optionally scaled by a constant value.
Load import from CSV file – Forces from an external comma separated values (CSV) filecan now be imported and applied. Two methods are provided: forces applied directly to faces and remote loads (both forcesand moments) applied to faces or spots. Forces and locations are specified in the global coordinate system. Multiple load cases can be specified in each CSV filealthough only one may be selected at a time.
Partial dynamic response – All dynamic time and frequency XY plots can now be filtered using a subset of the total analysis modes.
Dynamic reaction forces – Are now available in all dynamic analysis workflows.Can now display an XY graph of componentor resultant force/moment at both supports and part connections. Partial dynamic response is available to query the results.
New Adapt for stiffness and Adapt for stress solution settings –The solution settings dialog has been refactored to make it easier to understand for new or occasional users. Two new high-level adaption objectivesare now provided that specifies the overall speed vs. accuracy preference.Adapt for stiffnessis used for general load path prediction and modes.It performs 3 adaptive solution passes.Adapt for stressis used when refined stress prediction is required. It performs 4 adaptive solution passes and includes special logic for stress gradients at small local features or in thin curvedparts. In most cases, thesetwo high-level objectives are all that is required however a third objective, Custom, is provided for fine grained control and advanced convergence studies. Thehigh-level objective is now listed in the project tree as well as the results summary dialog.
Default contact conditionsnow in Connection workbench – Contact conditions (bonded, sliding, separating, disabled) can now be defined in the connection workbench and will be used across all appropriate design study analyses. Contact conditions may still be defined within an individual analysis workbenchand in this casewill override the default settings
Strain energy density – New result type now available.
Datum points – A datum point isa reference location from which subsequent results queries can be taken.Datum points sets can now be defined using the new Assembly workbench toolbar command. XYZ locations are imported from an external comma separated values (CSV) file. Datum point sets can be selected during post-processing in the Pick infodialog and are available forstatic, thermal and dynamic analyses

Enhancements

- Enhanced solution adaption – Solution adaption has beenimproved. Changes in solution settings will now invalidate but not remove prior results. Invalidated results, marked in red, may still be displayed and can now be compared to results with different solution settings. To compare results: run analysis 1, copy analysis 1 to analysis 2, change solution settings, run analysis 2, compareresults for analysis 1 and 2.
- Remote load initial location – The initial remote load location now defaults to the center of gravity of the selected faces. For example, the center of a cylindrical face. The point can then be dragged or edited on the dialog to offset it in the desired direction.
- XY Plots – Log and natural log Y axis scaling now available in frequency and random response analysis plots. Plot range limits now available on all plots.
- Review part connections – Now supports multiple part selection.
- Save part as STL – Individual parts may now be saved as STL.
- Improved virtual connector visibility – Virtual connectors (bushings, pins, remote supports, etc.) are now only visible when selected in the project tree. This now matches the methods used for regular connections.
- Connection tolerances – Connection tolerances have been improved. This should reduce the number of connections found on individual part faces.
- RMS stress contour – This is calculated for the entire frequency range.
- Save results to CSV – A Save to CSVbutton has been added to Pick info, Reaction forcesand Modal participation factorsdialogs.Dynamic analyses (time, frequency and random) are not supported at this time.
- Silent install – Installation can now be done from the command line. This is intended to centralize remote management and better support large installations. Command line syntax is: Simsolid-setup.exe /S /D=<path>where /Sindicates silent install and /Ddefines the installation folder. Note that /Dmust be the last parameter on the command line and the <path>string must not contain quotes even if the path contains blank spaces.Also note that allcommand line options are case-sensitive,so /Swill work, but /swon't.

Deprecated Features

- Removed – The results right mouse button option, Refine results on a face, has been removed. The purpose of this functionwas to add additional result contour sampling locationson thin walled structures. However, it did not work satisfactorily on other geometries.We are working to automate this functionality in the future
