General Changes:

• One can now use ED_ELEMENT and ED_CLASS during an INMODEL so long as the thing being edited has been defined.
• If one puts a blank line in a file, he no longer gets a list of the valid commands. The line is simply ignored.
• The wind force computations one gets when API is specified have been changed to comply with the 21 addition of RP2A.
• The code checking for a cone is now done in accordance with RP2A.
• A new command, &FILE, and a new string function &F_READ, have been added so that a user can now manipulate, open, close, read and write to files. Click Here to see the documentation, or Here to see a test.
• The options -CECHO, -QUERY, -MENCMD, and -COMO of the &DEVICE command no longer work, and the -USE_FILE option has been removed from the documentation. The work of this last option is now done with the &FILE command.

String Functions:

• New values: UPPER, LOWER, and SORT have been added to the string function &STRING.
• A new value, ATAN2 has been added to the string function &NUMBER.
• A new value, CDR has been added to the string function &ELEMENT.
• A new option, -PART has been added to the string function &COMPARTMENT.

Obstacles:

Fatigue:

• Fatigue is now computed not only at the ends but at then ends of all segments.

• an SN curve is associated with each fatigue point, and

• an SCF is associated with each fatige point.

You can now accumulate fatigue in the time domain as well as in the frequency domain. Click Here, to see how to define a duration for a time domain fatigue, and Click Here to see an example. Finally, there is now a &STATUS SN which will list the properties of the defined SN curves and the SCF reports now show the SN curve used and the SCF at the interior fatigue points. Click Here, to see an example.

Connectors:

Also, the GSPR has been changed so that one can specify "friction". Click Here to see the documentation.

Relative Motion:

Force Break Down:

These two "new types" of force now appear when you do a &STATUS FORCE or ask for reports on the breakdown of the forces. In addition, you will now get A_INERTIA, C_INERTIA, and SKIN_FRI. These correspond to added inertia, contents inertia, and skin friction.

What No Longer Works:

What Answers Will Change:

• Some answers may change due to the change in wind force computation for API wind treatment.
• The stresses and fatigue in cones will change.
