  • spurious
  • Indeed, these methods can suffer of undesirable limitations, such as ill-conditioning of the stiffness matrix, spurious or incorrect pressures and numerical locking (severe stiffening near the incompressible limit) [ 2 ], especially if low-order shape functions are adopted, due to the enforcement of the incompressibility constraint-i.e. the requirement that the displacement field is divergence-free.

  • flow
  • Besides a detailed numerical approach together with convergence studies for the highly nonlinear free boundary problem, we also compare the induced flow field of the motile cell with that of classical squirmer models and identify the motile cell as a puller or pusher, depending on the strength of the myosin-actin interactions.
