These are what we feel are some of the more important questions.

Q: Why did the answers change between REV X.XX and REV Y.YY?

Q: Why do I get the message "*** WARNING: EQUILIBRIUM NOT FOUND WITHIN TOLERANCE"?

Q: I have a rectangular barge modeled as a line of beams with a uniform load distribution. Why are the structural bending moments and shears not what I get from statics?

Q: How are the phases defined for RAOs?

Q: I am looking at MOSES results from the output report "CARGO G FORCE STATISTICS". Do these G forces include the g*sin(theta) effect? If so, how can the Longitudinal G force be reported as less than half of g times the maximum pitch angle?

Q: What does the message "*** WARNING: Negative On Diagonal Of Damping" mean?

Q: Where is the assumed center of rotation for vessel motions?

Q: How can I perform a time domain simulation in a new process which starts at the last event in an existing process?

Q: When I issue the command &STATUS FORCE, I get a several different types of forces listed, what are these?

Q: I have a system composed of several "things". Should I model them as a single body with several parts, or as separate bodies?

Q: Can MOSES compute the natural periods of a vessel?

Q: How can I add a damping of some percentage of critical?

Q: I have several members that are governed by "Hyd. Tension". How can this be since the structure is out of the water?

Q: What are the dimensions for radiation damping coefficients in the MOSES output?

Q: How does MOSES chose the phases doing a time domain simulation?

Q: Are the heave motions from the frequency domain coupled with rotations?

Q: Is the stiffness matrix (hydrostatic and connector) used in MOSES a 3 X 3 matrix with coupling terms, using the assumption of small motions?

Q: When starting up a job displays initializing and command line is blank but why not display a dialogue box with wait/progress bar or something animated to give the user a better clue to when he can begin?

Q: I notice that there are some glitches on the panel shading and water surface intersection in a GL picture. What is going one here?

Q: What is a .ppo file?

Q: When using #TANKER why do I sometimes get current and wind forces in a direction opposite of what I expect?

Q: How does MOSES do modal analysis?

Q: What are the properties of the water springs that MOSES automatically generates during an upending analysis.?

Q: What type of plate element does MOSES use?

Q: What is "Mom AMF" in the beam check summary output?

Q: Why doesn't the conversion between metric tons and kilo-newtons change when using SI units and changing the value for the acceleration of gravity in the program?

Q: When will EQUI_H and &EQUI give the same result?

Q: Why did the MOSES SACS converter did not properly convert my SACS loads?
