WebThis LS-DYNA simulation shows a simple 3D ICFD problem. It features a flow through a cylindrical pipe. Since the Reynolds number is laminar, a parabolic profile is expected at the outlet. It makes use of the ICFD_CONTROL_SURFMESH keyword to remesh the original surface mesh. The purpose of the ICFD_CONTROL_MESH in this input deck is to add more … WebAug 1, 2024 · This shock wave transforms quickly in seismic p-wave while travelling through the water at specific acoustic velocity. Hempen firstly uses ‘pressure waves’ as a general term to describe waves propagating through water regardless of distance from the source or velocity of shock wave [3].
