Supports

Restrain the degrees-of-freedom of selected nodes. Replace or remove the support conditions previously defined.

From the Main Menu select Model > Boundaries > Supports.

Select Geometry > Boundaries > Supports in the Menu tab of the Tree Menu.

Click to the right of Supports: Display the Support Table

 

 Boundary Group Name

Select a Boundary Group in which the specified boundary condition is included. Select "Default" if Group assignment is unnecessary. Click to the right to prompt the "Define Boundary Group" dialog box to add, modify or delete Boundary Groups.

 

Options

Add: Add new restraints to selected nodes

Replace: Replace previously defined restraints on selected nodes

Delete: Delete previously defined restraints on selected nodes

 

Support Type

Select the components of the degrees of freedom of the selected nodes to be restrained. The components correspond to the GCS (Nodal local coordinate system if it is defined) (refer to "Coordinate system and nodes").

D-ALL: All displacement degrees-of-freedom

Dx: Displacement degree-of-freedom in GCS X-direction (Nodal local x-axis direction)

Dy: Displacement degree-of-freedom in GCS Y-direction (Nodal local y-axis direction)

Dz: Displacement degree-of-freedom in GCS Z-direction (Nodal local z-axis direction)

R-ALL: All rotational degrees-of-freedom

Rx: Rotational degree-of-freedom about GCS X-axis (Nodal local x-axis)

Ry: Rotational degree-of-freedom about GCS Y-axis (Nodal local y-axis)

Rz: Rotational degree-of-freedom about GCS Z-axis (Nodal local z-axis)
