Here, we shows plots of (a) the force and torque imbalance, (b) the mean relative force error, (c) the compute time, and (d) the mean relative torque error against opening angle, θ, for each of the tested FMM schemes. The original, uncorrected FMM of D2000 is refereed to as “UC” (red squares), our torque corrected version is referred to as “TC” (blue circles), and our optimized torque corrected version is referred to as “TCO” (green triangles).
