Installing or Updating Intact.Simulation for Grasshopper¶
Download Latest Intact.Simulation for Rhino Grasshopper¶
Warning
Please follow these instructions each time you are installing or updating. Failure to do so may result in Intact.Simulation for Grasshopper not working properly.
If Rhino is running, close it.
Run the installer Intact_InstallerV*.exe.
Start Rhino and test the installation.
Changelog from Major Updates¶
Update: July 14 2025¶
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
Update: Nov 5 2024¶
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
Update: February 5 2024¶
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
Update: October 26 2023¶
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.
Update: July 27 2023¶
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.
Displacement Boundary Conditions for partial and non-homogeneous boundary conditions
Custom thermal material block <materials-label>
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).
