Key parameters for the SPAM vesicle simulation

Parameter Symbol Value
SPAM cutoff σ (10−6m) 1
Timestep δt (μs) 0.0001
LG parameter Γ* (μm2/μs) 2
CH parameter M* (μm4/μs) 20
Unit of mass m (10−16 kg) ρAh/N
Modulus λ0 (10−3 kg/(ms2) 5.4
Bulk modulus parameter ɛ 10 to 100
Membrane thickness h (μm) 0.0034
