(a) Average relative error for the forces acting on cylinders \(\langle |{{\mathbf {F}}^{\mathrm {H}}_{\mathrm {true}} - {\mathbf {F}}^{\mathrm {H}}_{\mathrm {pred}}}| / |{{\mathbf {F}}^{\mathrm {H}}_{\mathrm {true}}}| \rangle\) as a function of the cylinder number N. (b) Average absolute errors for the x- and y-components of the forces, \(\langle |{F^{\mathrm {H}}_{\mathrm {x, true}} - F^{\mathrm {H}}_{\mathrm {x, pred}}}| \rangle\) (red open circles) and \(\langle |{F^{\mathrm {H}}_{\mathrm {y, true}} - F^{\mathrm {H}}_{\mathrm {y, pred}}}| \rangle\) (blue closed circles), acting on cylinders as a function of the cylinder number N. The average values of x- and y-components of forces acting on cylinders obtained by numerical simulation, \(\langle |{F^{\mathrm {H}}_{\mathrm {x, true}}}| \rangle\) and \(\langle |{F^{\mathrm {H}}_{\mathrm {y, true}}}| \rangle\), are shown with red and blue triangles, respectively.
