Dear LS-DYNA professionals!
I'd like to simulate blast analysis using axisymmetric ALE using *SECTION_ALE2D, *EOS_JWL, *MAT_HIGH_EXPLOSIVE_BURN, and *MAT_NULL.
Unlike AUTODYN using Flow-out boundary conditon, LS-DYNA cannot assign boundary condtion for flow-out of air and gas from explosive material.
Even though *BOUNDARY_NON_REFLECTING_2D is assigned on boundaries, the result of analysis is not changed (reflection of pressure on boundary).
Please give me good advices to solve this problem.
