An adaptive approach to remove tensile instability in SPH for weakly compressible fluids
Kanishka Bhattacharya, Tapan Jana, Amit Shaw +2
Smoothed Particle Hydrodynamics (SPH) is plagued by the phenomenon of tensile instability, which is the occurrence of short wavelength zero energy modes resulting in unphysical clu…

A stable SPH with adaptive B-spline kernel
Saptarshi Kumar Lahiri, Kanishka Bhattacharya, Amit Shaw +1
Tensile instability, often observed in smoothed particle hydrodynamics (SPH), is a numerical artifact that manifests itself by unphysical clustering or separation of particles. The…
