How to achieve analysis of underwater explosion based on LBE+ALE?

  I have noticed that LS-DYNA currently provides an integrated LBE+ALE approach, which can more efficiently handle obstacles in air blast simulations. Based on this, I wonder whether the same method could be applied to analyze underwater explosions? In the LBE method, the blast pressure data is derived from the historical CONWEP air blast database. If I have corresponding underwater explosion data, could I use user-defined functions to implement underwater explosion analysis?

  Hi, are you aware of this guy below? Outside people in LSTC/Ansys who can't comment, this guy is probably the only other free source that one can utilize. I believe we can do underwater explosion with load_blast_enhanced and an SALE approach. However, I've not done enough studying to know what I am doing. I will get there one day though. Ameen Topa has some publicly availble lectures that touches this type of topic often and is a good resource to reach out to. I just want to share this in case it helps.
