Tamilvanan 0 Report post Posted August 21 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 Quote Share this post Link to post Share on other sites

Tamilvanan 0 Report post Posted August 22 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. Quote Share this post Link to post Share on other sites
Livil Lyle 92 Report post Posted August 23 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 Quote Share this post Link to post Share on other sites
Tamilvanan 0 Report post Posted August 23 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. Quote Share this post Link to post Share on other sites

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 Quote Share this post Link to post Share on other sites
