04.Set the Body Attributes and the Material Properties

We assign names to the body attributes and the material properties. Various parameters associated with them will be set up here, too.

The body attribute is required to be set on each body. Various specific data, such as the thickness in the 2D analysis, the width of the wire element, the coordinates for anisotropic material, can be set on the body attribute.

Body attribute is distinguished by its name. Therefore it is not allowed to assign the same name to the different body attributes.
 

Material property constitutes the body. The material data might vary depending on the simulation you try.

Material property is distinguished by its name. Therefore it is not allowed to assign the same name to the different material data.

 

Procedure

  1. Assign a name to the upper material.

    Highlight and click to select the upper material on the modeling window    .
     

 

  • To select a particular body out of several overlapping bodies, try the following methods:

 

    • Space Key Method

      Rest the mouse pointer on the overlapping area, and press the <Space> key.
      Body selection will change. The left-click will fix the selection.
       

    • List Selection Method

      Rest the mouse pointer on the overlapping area, and press the <Tab> key.
      The body selection list will appear. Select the body of your interest and left-click to fix the selection.


      For more details, refer to How to Select Body and Topology where you will find “Clicking the Mouse” and “List Selection Method”.

Selected

  1. On the [Attribute] context tab
    ,
    click [Body Attribute/Material Property] .

 

 

  1. In the [Body Attribute/Material Property Setting] dialog box,

    enter Body Attribute Name: upper

    select [06_Piezoelectric material] on Material DB and select [000_P-4]

    Then click
     

  2. Any name is acceptable.
     

  1. In the [Edit Body Attribute [upper]] dialog box

    go to [Direction] tab,

    select Vector and enter (X:0, Y:0, Z:1),

    and click .

    The polarization is set in the positive Z direction.

    Then click in the [Body Attribute/Material Property Setting] dialog box and exit.

     

  1. Assign a name to the lower material

    Highlight the lower material on the modeling window and click to select.

Selected

  1. On the right-click menu, click [Body Attribute/Material Property].

  1. In the [Body Attribute/Material Property Setting] dialog box,

    enter Body Attribute Name: lower.

    Select [06_Piezoelectric Material] on Material DBSelect [000_P-4].

    Click .
     

  2. Any name is acceptable.
     

  1. In [Edit Body Attribute [lower]] dialog box,

    go to the [Direction] tab,

    select Vector , enter (X:0, Y:0, Z:-1),

    and click .

    The polarization is set in the negative Z direction.

    Then click in the [Body Attribute/Material Property Setting] dialog box and exit.
     

The body attributes and the material properties have been set.
