How to get elements inside Database cross section plane

[Tamilvanan 0]

In dyna, I have a finite *DATABASE_CROSS_SECTION_PLANE. It is cutting some elements in the model. I would like get the elements cut by the cross section.

 

The cross section will have the following information.

1. Base node of cross section.

2. Plane vector

3. orientation vector

4. Size of the plane

Hi, 

 

*createmark elems 1 "on plane" "x y z i j k tol plane touching"

 

"

This command will select all the entities cut by the specified plane normal. But I should be able to select elements only cut by the plane.

I was able to do it with this command.

*createmark elems 1 "on plane" 0 6 0 0 1 0 1 1 1
hm_highlightmark elems 1 h

I think i have not explained the problem correctly. 

 

In attached image, I would like to get only the elems cut by the cross section i.e only the red comp elements.

 

I used the command provided, it is giving all the elems in the plane as highlighted in the image.

have you tried creating a mark by box? 

 

*createmark elems 1 "by box" x0 y0 z0 x1 y1 z1 syst location contained all tol

You can indicate selection on red comp only by

*createmark elems 1 "on plane" .....

*createmark elems 2 "by comp name" red_comp

*markintersection elems 1 elems 2
