# Parameter sweep: the We-De regime map at FIXED Ohs and FIXED Ec.
#
# Here the elasto-capillary number Ec = G*R0/gamma is held constant while
# We and De are swept. The polymer Ohnesorge number Oh_p = Ec*De then
# varies with De (equivalently the solvent fraction beta drifts), which
# isolates the role of the relaxation time at a fixed elastic modulus.
#
#     Ec = Ec (constant)                 (De = 0  ->  Newtonian, Ec = 0)
