Export Solid Element List in LS-DYNA Format

Hello,

I am trying to export a list of solid elements along with their assigned nodes in the following format:

*ELEMENT_SOLID
$# eid pid n1 n2 n3 n4 n5 n6 n7 n8
1 2 2 32 5 4 4 4 4 4
2 2 2 29 32 28 28 28 28 28
3 2 4 32 31 28 28 28 28 28
4 2 2 4 1 28 28 28 28 28
5 2 2 28 32 4 4 4 4 4

Here’s what I’ve done so far:

  1. Created solid elements from 3D elements exported from AVIZO.
  2. Extracted 2D faces from these 3D elements.
  3. Generated solids again from the 2D faces.
  4. Created node set lists for all faces of the 3D model.

However, when I exported the .k file to import it into LS-DYNA, the file did not include the required solid element list as shown above.

Could you please guide me on how to fix this issue and properly export the solid element list in the desired format?

Thank you for your help!

    Hello @Nafiseh ,

    can you please provide us information about the type of elements you are trying to create?

    According to the numbering sequence in your example, the 5th node is repeated 4 times, which leads to a degenerated element (a pyramid element)?

    Is it what you are trying to export to LS Dyna? When you mention you load it in LS Dyna, which software are you refering to? Is it LS-PrePost?

    Best Regards,

    Michael
