Release Notes
Altair SimSolid 2019.5, 23-JAN-2020
Highlights
• Highlights of this release include new structural adhesives, new dynamics results and new HTML based help. Continuing
the work done in release 2019.4, connections, contact conditions and solution settings workflows have been further
improved. Performance improvements have been made in fillet weld creation, graphics and CAD file reading. In addition,
many minor usability improvements have been made. See the feature descriptions below for more details.
New Features
• Adhesives – Structural adhesives can now be modeled. This provides stiffness to the connection based on a selected
material property. Two forms are possible. First, any standard connection can have adhesive applied. Right mouse button
select a connection in the Project tree, pick the Apply adhesive menu item and when prompted pick a material property.
This will apply structural adhesive to the entire connection.
Second, use the new Create adhesive function found in the connection toolbar. This will create adhesive connections from
existing tubular parts. Selected parts must conform to a tubular cylindrical shape. SimSolid will extract the centerline of
the part then create an adhesive region of a specified width in the gap between the parts that the tube overlaps.

Release Notes
Note, both forms assume that there is a finite gap between the parts to be connected. This gap will be used to calculate
the adhesive thickness. When the gap is too small, parts faces coincide or overlap the user will be warned and a minimum
thickness will be used.
• Dynamics results – Velocities and acceleration, both magnitudes and components, are now available for transient
dynamics (time domain only).
• Disconnected group of parts – This command has been extended to allow connection search on the boundaries of a
selected set of disconnected groups of parts directly within the dialog. To use, select two or more groups and pick the
Connect button.
• HTML Help – New browser-based help is now available and replaces the previous right panel help dialog. This standardizes
SimSolid with the help found in other Altair products and provides new features such as better graphics, enhanced table
of contents and help search
• Show/hide spots – A new display function now available to toggle spot symbol graphics On and Off.
• Altair ALM utility – The Altair security directory along with the ALM Utility are now included in the SimSolid installer and
may be invoked from the windows menu.

Enhancements/Performance improvements
• Solution settings – Are now specified independently for each analysis. This provides a more convenient method to do
analysis comparison and solution convergence studies.
In addition, there is an option to copy individual analysis solution settings to all studies.
• Connections & contact conditions – There are now separate review/editing dialogs for connections and contact
conditions. Right mouse button (RMB) select a part and pick the desired menu item to view.

• Connections & contact conditions – Default contact conditions have been removed from the analysis branch in the
project tree. Only custom contact conditions unique to a given analysis will now be listed. This greatly simplified the
Project tree containing multiple design studies and analyses. Custom contact conditions are defined from the Review part
contact condition menu item.
.
• Connections & contact conditions – A new option, Connections between parts in list only, is now available on the Review
part connections or Review contact conditions dialogs. This limits connections/contact condition to only areas shared by
parts listed in the Parts group. This makes it easier to focus on only the boundaries between a few parts.
• Pick info – Pick info is now available directly on the model – no prior result contour is required. Results quantities are
selected from the dialog and labels are updated on the model.

• Pick info – A new option is provided to output values in local cartesian or cylindrical coordinate system directions. Export
to CSV files now includes information for selected coordinate systems.
• Bearing load direction – Bearing loads can now be set in specified XYZ component directions. This provides more fine-
grained control of direction. Note that the load direction vector must have a non-zero component perpendicular to the
cylindrical bearing load axis.
• CAD pan/zoom/rotate mouse button mapping – New mouse button mappings are available for CATIA V5, UGNX, and
CREO. Select Settings>Mouse settings menu to change view model for current session. Select Set as default to change for
all sessions.
• Dynamics results – Peak responses are now calculated for all result quantities. As an added option, Pick Info can be used
to create graphs without first displaying a contour plot of a quantity. This greatly accelerates response graph evaluation
for large assemblies.
• Dynamics results – Output of Von Mises RMS stress for selected frequency upper limit. Upper limit set by slider on
animation response dialog.

• Stress concentrations – Stress concentrations of very small torus shaped surfaces is now greatly improved. This is most
common in cylindrical notches or other axisymmetrical parts. This works with all adaption levels including the base level
Adapt for stiffness.
• Graphics performance – The display of Connections and Boundary condition symbols has been improved. This will be
most noticeable on large models with many entities.
• Seam Weld performance – The search performance when creating seam welds has been improved.
• Local connections at bolts – A new option is provided to localize connections on plates with bolts. This limits the bonded
connection area between the plates and, in turn, reduces the overall joint stiffness.

• Reaction forces – Multiple selection of parts in reaction dialog is now supported.
• Elastic modulus handling for nonlinear materials – When a material has a stress-strain curve defined in the material
database, we now disable the elasticity modulus field for editing. The elasticity modulus value is derived from the stress-
strain curve itself. For old projects where the user has a curve but also has edited the elasticity modulus to something else,
the value is automatically re-evaluated when they click OK in the strain-stress curve dialog. Whenever we use the elasticity
modulus in the solver, if there is a stress-strain curve, we will use the value derived from the curve.
• Supported CAD import formats – The list of supported CAD formats has been updated. New is support for SOLIDWORKS
2019, CATIA R29, Creo 6 and NX CR. The current list of formats and versions is as follows:
CAD file format Supported Versions
CATIA V4 (.model, .dlv, .exp) All 4.xx
CATIA V5 (.CATPart, .CADProduct) R10 → R29
CATIA V6 (.3Dxml) 2011 → 2013x

• Add new part connections – When additional parts are added to a Design study, a new option will now be presented to
add connections only between these parts and exiting adjacent ones. Existing connections will not be modified.

Resolved Issues
• Improved – Solution settings for linked thermal-structural analysis are now completely independent from previous
thermal analysis.
• Improved – SimSolid no longer allows separating-closing contact for connections with penetrations or without gap. This
will be changed to separating contact during editing.
• Improved – Connection evaluation search has been improved for small faces.
• Fixed – Several issues relating to seam welds.
• Fixed – Issue relating to incorrect Z-clipping of graphics displays at certain zoom levels.
• Fixed – Entity graphics selection is now independent of zoom level.
• Fixed – Issue relating to nonlinear analysis with separating contact.
• Fixed – issue where Foundation factor/Support stiffness did not show correct values when the spring support dialogue is
launched in edit mode.
• Fixed – Issue relating to nonlinear analysis postprocessing. SimSolid now shows correct contact condition when reviewing
response with separating contact.
• Fixed – Multiple issues relating to solver crashes.
