ϕcp = 0.9036 is the close packing volume fraction. The reference data is adapted from [7], generally accepted as the ground truth for rigid Brownian liquid crystal equation of state. Simulations using linearized WCA potential uses the code by [8], which has a constant repulsive force when the distance between rods is smaller than 0.812DMT, where DMT is the microtubule diameter.
