The DisplacementBC block in Intact.Simulation for Grasshopper can fix displacement over some surface. Restraints are applied to faces of components participating in the simulation by connecting to the Restraints input on the stress solver component. Displacement along each axis can optionally be fixed to some value. If a value is not specified, the axis will be un-restrained.

A DisplacementBC block has four inputs:

• the geometry of the surfaces over which to fix displacement (must be specified)
• the value to fix displacement at along the x-axis (optional)
• the value to fix displacement at along the y-axis (optional)
• the value to fix displacement at along the z-axis (optional)

The output should be given to the Load input on a Stress Solver block.

📌 See example application Ex-4: Displacement Boundary Conditions

In the following example we have a stress scenario with the following elements.

• One component
• One fixed restraint
• One displacement boundary condition, which fixes only the x-axis at 1.0 (and slides along y- and z-axis)
