The Repeated Replacement Method: A Pure Lagrangian Meshfree Method for Computational Fluid Dynamics

Integral error norm vs. maximum pressure error metric.
Maximum integral error norm emaxinorm and the maximum number of cells nmax vs. the maximum pressure error metric Δmax p for Sod’s problem. Δmax p is swept from 1.0e-1 to 1.0e-5, while Δmax ρ and Δmax u are held constant at 1.0e-1. Simulation was from time t = 0.0 to t = 1.5. This figure shows that the error cannot be decreased past a certain point solely by adjusting Δmax p, since there is little pressure gradient across the contact (where most of the error is concentrated in this test).
