Hi Ram,

There is an ALE Domain object in WB LS-Dyna to create a surrounding mesh that the fill material can flow through. Suppose the process runs in the air. What material I should assign to the domain? If it is the air, how to add the vacuum material to the ALE group? The only way I see is to create some dummy body inside the group to introduce the vacuum (by the way this approach works...no error message appears) but I'm not sure that it works correctly from the point of view of physics!

Thanks
