SALE Air Blast Pass Through Structure No Deformation

Hi everyone, I recently encountered a problem with my SALE model for sandwich panel air blast simulations. I followed some videos and official keyword guidelines to set up the blast model, and the structure is a simple sandwich panel. The model runs smoothly, but when checking the results, I found that the blast wave passes through the structure, and the sandwich panel structure has no deformation. I have debugged for over a week with no progress. Has anyone encountered a similar situation? I would greatly appreciate any insights or suggestions. Many thanks!

Please see the attached figures for the problem results.
