Hello, everyone. I found something strange when calculating the blast wave while using S-ALE.  <\/p>\n

I followed Dr. Hao Chen’s tutorial and instead of setting the PREF in CONTROL_ALE to atmospheric pressure, I set the air to one atmospheric pressure in the PREF of ALE_STRUCTURED_MULTI-MATERIAL_GROUP.  In the calculation process, the pressure in the detonation product becomes 0, as shown in the figure. The detonation products will continue to expand, filling the entire domain, and the ambient pressure will be zero. The boundary conditions use BOUNDARY_SALE_MESH_FACE, where two edges are symmetric faces and two are non-reflective boundaries. ALE_STRUCTURED_MESH_VOLUME_FILLING was adopted to set explosive charge.<\/p>\n

Welcome to the discussion.<\/p>\n
