How to get elements inside Database cross section plane

Tamilvanan

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

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 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.

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
