Restraint

Select constraint under the tools menu to enter the constraint setting window, or click Constraints Shortcut button to enter the constraint window.

Wheat chestnut provides two kinds of constraints: fixed constraint and displacement constraint. The fixed constraint is a full constraint. For the solid, i.e. the constraints x, y, Z have three degrees of freedom, and for the shell, i.e. the constraints x, y, Z, Rx, ry, RZ have six degrees of freedom. Displacement constraints can constrain the selection of displacements in different directions. In static calculation, the displacement is usually defined as 0 or free. Constraints can be applied to geometric points, lines, and faces.
