    Final results

     1,1,1,2-tetrafluoroethane
    CAS 811-97-2
    formula C2H2F4
    Molar mass (g/mol) 102.03
    Liquid density at T = 0.7 Tc (mol/m^3) 13045.20

    The parameters available are shown below. In this case the correlation gives sensible results for several segment numbers. Choosing the best one is a tradeoff. There should be roughly three atoms per segment, not counting hydrogen. The topology (e.g. the length to breadth aspect ratio) of the coarse-grained model should match the topology of the original molecule.

    Clicking "raaSAFT script" gives you a Python implementation for simulating this with raaSAFT, our SAFT-γ Mie framework for running MD simulations with HOOMD-blue (well-supported) or GROMACS (new feature). See the raaSAFT webpage for how to install and use raaSAFT.
