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

 

Ansys employees cannot answer this type of question.

 

Please wait for other forum members that might have experience with this type of applications to provide some feedback.

 

 

Thank you

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.
