The analysis starts from the kernel-based approximations inherent to the SPH method. An explicit kernel correction is proposed, which approximately achieves first-order consistency. The suggested approach is additionally combined with a Eulerian variable resolution approach, which conserves the number of particles but changes the individual particle mass in a transit regime. Validation studies featuring fully wetted and free-surface flow configurations are employed to assess the benefits of the combined approach. Results indicate benefits of the kernel correction and display merits and drawbacks of the variable resolution approach.en0955-7997Engineering analysis with boundary elements2019555570An approximately consistent SPH simulation approach with variable particle resolution for engineering applicationsJournal Article10.1016/j.enganabound.2019.06.001Other
