Getting dropped
Preparing to demonstrate a drop test the other day, I was reminded of a useful procedure for creating a suitable mesh and thought you might like to know about it.
- Identify the surface that will hit the ground first during the drop test.
- Create a static study.
- Add a fixed restraint to the surface identified in the first step above.
- Apply a reasonable gravity loading (e.g. 10g).
- Then run an h-adaptive study with a fine accuracy setting.
- Create the drop test study and then drag and drop the mesh from the static study on to it.
- Continue with the drop test.
By using an h-adaptive mesh, you should find the elements are refined in the regions most suitable for the drop test. Sneaky but cool.
