1. “PrescribedDisplacement.m”

Produces “.dat” files of parameter data for the system of a single line of neo-Hookean incompressible viscoelastic cells subject to a prescribed displacement.

Files saved as:
‘K#1_#2_PD_#3.dat’
for individual simulations over time with eta = 0 where #1 is the value of K, #2 is either D (discrete system), C (continuum) or A (analytical) and #3 is the variable saved (x (boundary/node locations), xc (cell centre of mass, discrete), p (pressure), lambda (stretch), t (time)).
Or Files saved as:
‘eta#1_#2_PD_#3.dat’
for individual simulations with K=0. #1 is the value of eta, #2 and #3 are as above.

Files saved as:
‘#1_#2_PD_#2.dat’ 
for solutions against K or eta values (saved as ‘K_PD_Ks.dat’ and ‘eta_PD_etas.dat’ respectively) where #1 is either K (i.e. eta=0) or eta (K=0), #2 is either D (discrete), C (continuum) or A (analytical) and #3 is the variable saved (MaxP (maximum pressure in array), MinP (minimum pressure in array), MinLambda (minimum stretch in array), L (array length)).

2. “GrowthWithK.m”

Produces “.dat” files of parameter data for the system of a single line of neo-Hookean incompressible viscoelastic cells subject to stress-driven growth with non-zero substrate damping.

Files saved as:
‘K#1eta#2_SG_#3_#4.dat’
for individual simulations over time where. #1 is the value of K, #2 the value of eta, #3 is either D (discrete system) or C (continuum) and #4 is the variable saved (x (boundary/node locations), alph (elastic stretch), p (pressure), sig (stress), t (time)).

Files saved as:
‘#1_SG_#2.dat’ 
for solutions against K or eta values (saved as ‘D_SG_Ks.dat’ and ‘D_SG_etas.dat’ respectively) where #1 is either D (discrete) or C (continuum), #2 is the variable saved (MaxP (maximum pressure in array), MinP (minimum pressure in array), MinAlpha (minimum stretch in array), L (array length)).

for individual simulations over time where. #1 is the value of eta, #2 is either D (discrete system) or C (continuum) and #3 is the variable saved (x (boundary/node locations), alpha (elastic stretch), p (pressure), sig (stress), g1 (growth in x direction), t (time)).

Files saved as:
‘eta_#1_SG_#2.dat’ 
for solutions against eta values (saved as ‘eta_D_SG_etas.dat’) over time where #1 is either D (discrete) or C (continuum), #2 is the variable saved (MaxP (maximum pressure in array), MinP (minimum pressure in array), MinAlpha (minimum stretch in array), L (array length)).
