Inquiry for non-reflecting boundary for blast analysis using ALE

    • Taylor G

      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.
