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.

1. If Rhino is running, close it.
2. Run the installer Intact_Installer-EvaluationV2023.07.27_0.1.14.exe.
3. Start Rhino and test the installation.

• 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).
