Convergence of the prestress algorithm. After prestretching, G&R is activated with unchanged boundary conditions. a Maximum Euclidean norm of the nodal displacements between the reference configuration and the prestressed configuration for different convergence thresholds. After the subsequent G&R phase, the maximum Euclidean norm of the nodal displacements is around half of an order of magnitude higher than the chosen prestress convergence thresholds. b Maximum relative deviation of the myocyte fiber Cauchy stress from the homeostatic stress for different convergence thresholds
