FIX_END:

FIX_END and PIN_END are two approaches to the same problem of a single beam subjected to a sea. For FIX_END the beam is "fixed" at the seafloor. The answers should "be the same" as those of the test PIN_END but they are not. The difference is a starting transient which decays more quickly for the PIN_END case. This is because it uses constraints while the FIX_END case uses flexible elements. Also of note is that this test is quite sensitive to the values of the stiffness. Increasing stiffness an order of magnitude or so will yield quite unacceptable results.
