3D displacement

The 3D displacement command serves for displaying deformations on selected 1D and 2D members. (not only results from linear and nonlinear analysis, but also deformations of modal and stability eigenmodes)

Usage

  1. Calculate a FEM analysis of the model
  2. Go to Tree > Results > 3D displacement
  3. Set properties of the command to specify mainly:
    • selection of 1D and 2D members where the results are evaluated
    • load type from which the results are derived
    • specific result value from the available list to be visualized
  4. Click on [Refresh] action button to display the results

Note: To get general overview about how to work with Result service and its commands, see Results/Basics.

Properties

Category Property Description / Notes
Selections

Type of selection

All / Current / Advanced / Named Selection / Design group

Specifies on what members the results are displayed

See "Type of selection"

 

Filter

See "Filter"
Location

In nodes no avg. / In nodes avg. on macro

Defines location in finite element mesh of calculated 2D values .

Value

u_x / u_y / u_z / f_x / f_y /f_z / U_total

See table Values below.
System

LCS mesh element / Global

Defines in which coordinate system the results are displayed.

Extreme 1D

Fiber / Section / Cross-section / Design group / Member / Global

Defines for which extreme on 1D member the results are displayed.

Extreme 2D

Mesh / Surface / Member / Global

Defines for which extreme on 2D member the results are displayed.

Result case Type of load

Load case / Combinations / Classes / Nonlinear Combinations/ Stability Combinations / Mass combinations

Defines for what load the results are displayed.

See"Result case"

Envelope (for 2D drawing)

Minimum / Maximum / Absolute extreme

Defines for which maximums the results are displayed. Available only for Combinations and Classes

Wireframe

On/Off

if check box turns ON that only centre lines and centre planes are used for calculation and displaying the results. This option is much less demanding on performance resulting to faster visualization of the results and deformed shape of structure. "Wireframe result model"
Calculate results on ... 1D members

On / Off

It is possible to switch ON/OFF drawing of results on 1D members or faces of 2D members.

positive face is the face which is on +z local coordinate of the 2D member

negative face is on -z local coordinate of the 2D member
2D positive face

On / Off
2D negative face

On / Off
Deformed structure Deformed structure

On / Off

The result values can be displayed also on deformed surface of the structure

The deformed surface is displayed for the combination from selected result case which provides the extreme value of selected magnitude. In case the result type contains envelope combination (different combinations can give extreme values for each member of the structure) it is possible to select between "Member deformation for global / local maximum".

Note:

Member deformation for global maximum means that the deformation of surfaces is calculated just for one exact combination which gives global extreme of selected magnitude.

Member deformation for member maximum means that the extreme combination is evaluated for each member separately. In this case the deformed surface can be displayed for different combinations per each member and there can be discontinuities in deformed surface.
For drawing use linear rotation

On / Off

Enables to switch between small displacement assumption based linear translations (which provides result consistent with used assumption) and circular translations (which keeps the original shape of cross section).
