• Select the symmetry surfaces and insert a Frictionless support.
– Since the geometry is 3D, a frictionless support is the same as applying a symmetry boundary condition.
Workshop 1 – Project Schematic
• Import the geometry file
– Flywheel.igs
• Edit the Model cell to open the Mechanical application.
