The LAMMPS-SPH water_collapse is an 2D example with external input data. My goal is to do a similar 3D version.
o-- So first I wrote a 2D input script “input.2d”, and I specified the initial particle locations within the input script. It works fine as shown in the attached figure “visit0000.png”.
o-- But when I tried to extend my 2D input into 3D as “input.3d” by extend the z-direction, I met trouble, as the initial pressure is too huge. The initial particle spacings in 3D are the same with the 2D version (meaning no particle overlapping), and the other parameters are not changed. I kind of wonder what might be the cause of the failed initial setups.
Thanks a lot in advance for sharing any user experience with LAMMPS-SPH.
