User input kinematics for floater in FAST

Dear Jason,

Thanks for your quick reply. I am using FAST v8.12.00a-bjj with HydroDyn v2.03.00c-adp.

As specified in the HydroDyn manual, my 7 wave kinematics files have WaveTMax/WaveDT=60/0.001=60000 rows and as many columns as internal nodes in the HydroDyn summary file. The .Elev file originally had also 60000 rows and NWaveElev=1 columns, and only numerical data. When I ran FAST with these files and WaveMod=6, it crashed with this error:

However, FAST runs if I add one more row to the .Elev file. In this case, the simulation ends normally and results make sense. Only that the wave elevation in the FAST output does not match the one in .Elev file (as in my previous message).

Second-order waves
