Fig 6. Concepts behind the MultiPatch model.
Panel A represents one of the patches making up a wall, with its area Ap,j being defined on the mid-wall surface. The mid-wall tension Tw acts on this surface. The patch is also assigned a volume Vp,j. Panel B demonstrates the difference between the patch areas Ap,j, Ap0,j, and ApRef,j in terms of sarcomere behaviour.
