All literature I look at use different values, and some papers only define C0 and C1 whereas others define C0 through C6. When I use these values my results are terrible. If, however, I choose to use EOS_MURNAGHAN my results look a lot better visually but my pressure readings which I am verifying against a paper are off.&nbsp;<\/p>\n<p>Can someone explain to me why different papers use a different EOS_LINEAR_POLYNOMIAL if they are both simulating water? Also, would it be possible to provide me with the values for the EOS in the kg-m-s-Pa unit system?
