A_SEA:

This example shows how to use the -A_SEA option of &ENV. There are six environments defined: HEADB, HEADL, HEADC, HEADA, BEAMB AND HEADBEAM. All have the same period, and the first four are head seas, BEAMB is a beam sea and HEADBEAM is obtained using -a_sea to combine HEADL and BEAMB. HEADC has a height that is the square root of the sum or the squares of the HEADB and HEADL. The HEADA is defined as the "sum" of the first two; i.e. it has a -sea which is the first and -a_sea which is the second.

Also, it demonstrates that the results for cargo force statistics and beam loads are the same for HEADA and HEADC, and results for headc are the the rms of those for HEADL and HEADB. Finally, it shows that the wave drift forces of the "A" cases are the same as the sum of the drift forces the the base cases.

B_KEELS:

These files demonstrate how to add bilge keels. The barge is disturbed to a 10 degree roll. The resulting oscillatory motion is analyzed to calculate a damping ratio. The data file uses a barge from the vessel library, defines some bilge keels. Bilge keels are modeled two ways: first using a load group using the the #PLATE class and second using structural plate elements. The barge is disturbed to a 10 degree roll and then left to oscillate. The oscillation from both models is then plotted on the same graph for comparison.
