Extended Data Fig. 3: Infinitely long, repeating wavy bend wall model (section ‘Wavy bend wall model’).

a, Initial splay-bend parameter (S_SB) field with repeating model bend walls in purple, with same colourbar as Fig. 3a. b, Resulting \({\mathcal{Q}}\) of steady-state active flows due to fixed S_SB from a. c, Resulting steady-state S_SB due to fixed flows from b. d, Resulting steady-state flows due to fixed S_SB from c. Director field is shown as black lines, the velocity field is shown as grey arrows and contours where \({\mathcal{Q}}=0\) are shown as solid lines.
