Changes:

• Reaction forces: Add a “Loads” output to Stress Simulation block which outputs the reaction forces and moments, and the applied forces and moments, to better perform load balance checks on a simulation
• Improve the material input validation, for example to prevent a thermal material being used as input to a stress simulation
• Allow unit system to be specified for displacement boundary condition, instead of using the document's unit system
• Create simulations in an asynchronous task, which is killed when the solution expires, to prevent hundreds of simulations from starting and running
• Improve support of Rhino geometry types
• Display a timer showing how long simulation has been running
• Provide better solver setting defaults by using an iterative solver
• and more

Bug fixes:

• When using a list of loads, apply the selected unit system to all loads
• Fix units in display of temperature field
• and more

• Added topology optimization with a new LevelOpt block. See documentation here
• Improve the error message when no simulation results are available for visualization
• Correctly display the direction of vector load glyphs
• Fix issue when applying a single displacement boundary condition to multiple boundaries

• Plugin update for Rhino 8 (will not work with Rhino 7)
• Auto and Manual mode to the solvers: a new Boolean input to each solver to control if it solves automatically or requires manual intervention. See automation for more information and Ex-6: Automation of a variable geometry heat sink for example files.
• Support for List input for easily specifying a large number of loads, or composite plies with different orientations, for example. More information can be seen at Using lists for Intact components.
• Allow material as input to sampler block, to allow sampling multi-material assemblies. For up to date information on this component block see Solution Sampler.
• When reading an archived solution, display glyphs to indicate the boundary conditions
• Pretty print simulation scenario configuration for archived solutions

• Support for Orthotropic materials with a vast database of Composites and Wood materials. See Supported Materials for more instructions and Ex-B4: Static Simulation of a Composite Motor Mount and Orthotropic Laminate Plate Stress Analysis for example files.
• New Sliding Boundary Conditions that constrain motion normal to a surface and only allow sliding along the surface. Use it to apply rotational sliding on a cylindrical face. See Sliding Boundary Condition for instructions and Ex-8: Cylindrical Sliding Boundary Conditions for example files.
• Now you can apply Hydrostatic pressure load to model varying pressure with the depth of fluid for your marine and other applications. See Hydrostatic Loads for instructions and Ex-9: Hydrostatic Loading Conditions for example files.
• Unit system bug fixes and enhancements: see the correct unit in the panel attached to custom material blocks. Right-clicking on blocks with units will now show the appropriate unit for the block instead of the default unit system.

• Improvements to Units handling. (Now specify units independently to, for example, loading condition blocks)
• Support for VDB Models. An example problem can be found here.
• Specify number of CPU threads for the solver to use
• Free-Free Modal Simulation
• Displacement Boundary Conditions for partial and non-homogeneous boundary conditions
• Custom thermal material block
• Solver Settings block now uses cell size if resolution and cell size are both defined.
• Added warning if visualization block is unable to read the solution after solving.
• Analytics are now collected. Details can be found in permission page during installation.
• Panels can now be connected to blocks for additional information (see video below).
