A set of constants defining the cell stiffness for various deformation modes. The presentation and derivation of these constants are presented in the validation paper: https://doi.org/10.3389/fphys.2017.00563.
Note that these parameters are not unique, i.e. multiple combinations of the constants can result in validated cell behaviour.
The current set of parameters is slightly different as presented in the original publication, specifically MaxCellBendingAngle has been reduced to achieve improved stability when RBCs are subjected to high shear flows. Although this results in slightly stiffer cell mechanics, the obtained force-displacement curves are still within the range of the validation data. For reference, please refer to examples/stretchCell.
All parameters are expressed as their squared value to prevent computation of the square at each evaluation.
