Creates a FEM constraint for a fixed geometry entry by locking all 6 degrees of freedom of the selected object.

There are several ways to invoke the command:
- Press the ConstraintFixed button.
- Select the Model → Mechanical Constraints → Constraint fixed option from the menu.
In the 3D view select the object the constraint should be applied to, which can be a vertex (corner), edge, or face.

You cannot mix object-types within the same constraint. Use one fixed constraint for each object type.

Materials: Solid, Fluid, Nonlinear mechanical, Reinforced (concrete); Material editor

Element geometry: Beam (1D), Beam rotation (1D), Shell (2D), Fluid flow (1D)

Constraints

Mechanical: Fixed, Displacement, Contact, Tie, Spring, Force, Pressure, Centrif, Self weight

Mesh: Mesh Netgen, Mesh GMSH, Mesh boundary layer, Mesh region, Mesh group, Nodes set, Mesh to mesh

Solve: CalculiX Standard, Elmer, Mystran, Z88; Equations: Deformation, Elasticity, Electrostatic, Electricforce, Magnetodynamic, Magnetodynamic 2D, Flow, Flux, Heat; Solver: Solver control, Solver run

Results: Purge, Show; Postprocessing: Apply changes, Pipeline from result, Warp filter, Scalar clip filter, Function cut filter, Region clip filter, Contours filter, Line clip filter, Stress linearization plot, Data at point clip filter, Filter function plane, Filter function sphere, Filter function cylinder, Filter function box

Utilities: Clipping plane, Remove clipping planes, Open FEM examples; Mesh clear, Mesh display info

Additional: Preferences; FEM Install, FEM Mesh, FEM Solver, FEM CalculiX, FEM Concrete; FEM Element Types
