DRAG MESH

 

This function generates elements based on the selected element pattern.  One-dimensional elements will be dragged to form plate elements, and two-dimensional elements (plate) will be dragged to form solid elements (prism).

 

Note:     In eta/DYNAFORM, only the same types of elements can be included in a part.  For example, if the current part contains plate (shell) elements, the user cannot create any solid elements in this part.  eta/DYNAFORM will display a warning message in the prompt window to alert the user.

 

1.        ONE LINE DRAG

 

l       Select the elements for the drag pattern by using the options in the SELECT ELEMENT dialog window.  See Figure 4.3.3 of Section 4.3.2, PART/ADD ELEMENT.

 

l       Select a line.  If the number of points is n, n-1 elements will be generated for each pattern element.

 

l       The user can accept, reject, or remesh. 

 

2.        NORMAL DRAG

 

l       Select the plate element pattern by using options in the SELECT ELEMENT dialog window.  Enter the thickness of normal drag and the number of layers in the POP-UP dialog windows.

 

l       The user can accept, reject, or remesh.

 

Note:  Plate element normals should be consistent in the drag pattern prior to the execution of NORMAL DRAG.

 

3.         3 OR 4 LINE DRAG

   

l       Select the plate element pattern by using the options in the SELECT ELEMENT dialog window.

 

l       Select three or four control lines to form a volume with the drag pattern. The user must select the control lines in clockwise or counterclockwise order.

 

l       Enter the number of layers.

 

l       The user can accept, reject, or remesh.
