Basic Operation

Run Grasshopper by typing Grasshopper at the Rhino command line
Navigate to the Intact.Simulation Toolbar in Grasshopper
Select a Solver for the the physics of interest (stress, thermal*, modal*)
Add components and assign material
Apply boundary conditions (restraints and loads)
Click Solve to compute simulation results
View results by connecting the results viewer

Stress Simulation

Insert stress solver block
Specify resolution using number input
Insert simulation component block
1. Specify geometry
2. Specify material
3. Connect components to stress solver
Insert restraint block
1. Specify surfaces to restrain
2. (Optional) select directions to restrain
3. Connect restraints to stress solver
Insert surface load block of choice (bearing load shown)
1. Specify surfaces to load
2. Specify load particulars
3. Connect loads to stress solver
Click [Solve] on stress solver component
Insert visualization block
1. Connect output of stress solver
2. Select solution quantity of interest
