Identification of Viscoelastic Constitutive Parameters of a Cell Based on Fluid-Structure Coupled Finite Element Model and Experiment

Table 3

Convergence analysis of fluid-structure interaction model of cell shear flow with 5 different mesh sizes.

	0.1μm	0.2μm		0.4μm		0.8μm		1.6μm
	Calculated Value	Calculated Value	Error	Calculated Value	Error	Calculated Value	Error	Calculated Value	Error
Shear Stress (Pa)	2.38	2.3	-3.36%	2.2	-4.35%	2.03	-7.73%	1.77	-12.81%
Maximal Pressure (Pa)	3.56	3.58	0.56%	3.59	0.28%	3.7	3.06%	3.86	4.32%

Note: refers to the relative error between the calculated value under the mesh density and that under the adjacent fine meshes; and all the physical quantities are from the highest point of the cell.
