REV NO: REV 509.001
DATE: March 12, 1999 Discovered By: R. Nachlinger
Description Of Problem

INMODEL is still inefficient for large models.

REV NO: REV 509.003
DATE: March 16, 1999 Discovered By: Frank Yang
Description Of Problem

The tolerances are not tight enough to accurately compute the line length given the tension for very shallow water.

REV NO: REV 509.004
DATE: March 31, 1999 Discovered By: R. Nachlinger
Description Of Problem

The left mouse button does not work correctly in some pick boxes (Manual Help, Contents, and Index).

REV NO: REV 509.005
DATE: April 01, 1999 Discovered By: Paul Dixon
Description Of Problem

The &STATUS CG_COMPARTMENT is incorrect when compartments are in moved parts.

REV NO: REV 509.006
DATE: April 06, 1999 Discovered By: Roger Burger
Description Of Problem

The Strucad converter does not handle the default behavior for E and Fy correctly.

REV NO: REV 509.007
DATE: April 12, 1999 Discovered By: Paul Dixon
Description Of Problem

If one has panels created which are composed of triangles, each of which has an area less than 40 sq inches, then the panel will not be emitted in the &SURFACE Menu.

REV NO: REV 509.008
DATE: April 23, 1999 Discovered By: Steve Paulson, Peter Lai
Description Of Problem

The concepts of -minimum and -correct are mutually exclusive. This causes problems of not being able to find equilibrium with tanks at -minimum. With this release, there was no correction of the gm, but the cg was computed correctly. This change "turns off" -correct for tanks at -minimum. It has a problem, however, in that the forces here will not be "correct" when doing a stress analysis.

REV NO: REV 509.009
DATE: April 23, 1999 Discovered By: Paul Dixon
Description Of Problem

No error checking was done to determine if the vertices of a panel belonged to the proper part. This adds such a check. Before if one defined a panel with vertices belonging to a different part, it created havoc with the database and any answers received were likely to be rubbish.

REV NO: REV 509.010
DATE: May 10, 1999 Discovered By: Mr. Huber
Description Of Problem

The way in which -SCFs are handled for beams which are not tubes is incorrect.

REV NO: REV 509.011
DATE: May 11, 1999 Discovered By: John Wetherhead
Description Of Problem

For large residual models (3200 degrees of freedom), MOSES will abort with a RAN OUT OF SPACE message.

REV NO: REV 509.012
DATE: May 26, 1999 Discovered By: Curtis Owens
Description Of Problem

If one applies large concentrated loads on both ends of a beam, there is a numerical problem in the "rigid body mechanics" part of MOSES.

REV NO: REV 509.013
DATE: May 26, 1999 Discovered By: Ray Nachlinger
Description Of Problem

In some rare circumstances, MOSES may have a segment violation. This occurs when the function heap must be resized in the middle of an append database transaction involving character data.

REV NO: REV 509.014
DATE: June 06, 1999 Discovered By: Ray Nachlinger
Description Of Problem

The MOVE command in the Connector Design Menu may not work properly if one has multiple bodies.

REV NO: REV 509.015
DATE: June 06, 1999 Discovered By: R. Nachlinger
Description Of Problem

It may be possible to have the "Default Body" set to GROUND. This confuses MOSES.

REV NO: REV 509.016
DATE: June 06, 1999 Discovered By: John Wethered
Description Of Problem

If one defines a system, stores an event and then repeats the process several times, MOSES will loose track of the connector activity. This is a quite involved problem and this may not totally fix the problem. It is best to not do this; i.e. define all connectors before storing events.

REV NO: REV 509.017
DATE: June 09, 1999 Discovered By: Roger Burger
Description Of Problem

For some situations, one can get a segment violation when doing an &instate -event. This occurs only when one of the buffers needs to be resized, but the basic data does not.

REV NO: REV 509.018
DATE: June 09, 1999 Discovered By: Larilla Templeton
Description Of Problem

If one has a long compartment description (longer that 30 characters) then he will get a fatal error on a Windows machine then doing tank capacities.

REV NO: REV 509.019
DATE: June 10, 1999 Discovered By: Paul Dixon
Description Of Problem

If one computes tanks capacities in SI units with a specific gravity of 1, the weight in the tank is not the same as the volume - it is too small by 1.0002623. This is due to the conversion factor from specific gravity to density.

REV NO: REV 509.020
DATE: June 22, 1999 Discovered By: Greg Hook
Description Of Problem

The use of a "power law" wind profile with a wind "table" load group produces bad results. The problem is that the height at which the wind was computed was "just above" the water surface. With this fix, the wind speed will be computed at the standard wind height (10 meters).

REV NO: REV 509.021
DATE: June 22, 1999 Discovered By: ETPM
Description Of Problem

The command BEAM ENVELOPE -DETAIL does not work properly.

REV NO: REV 509.024
DATE: July 08, 1999 Discovered By: J.L. Benoit
Description Of Problem

Sometimes MOSES get into a recursive loop. This happens when one get an i/o error and MOSES tries to write an error message which also causes an i/o error.

REV NO: REV 509.025
DATE: July 26, 1999 Discovered By: Georgina Moldonado
Description Of Problem

A &COMPARTMENT -NO_FLOOD @ will change filling types of compartments which are not flooded.

REV NO: REV 509.027
DATE: August 07, 1999 Discovered By: Paul Dixon
Description Of Problem

If one used a small number of periods, the interpolation of the wave drift force may not be correct.

REV NO: REV 509.028
DATE: August 24, 1999 Discovered By: ETPM
Description Of Problem

On AIX 4.2 MOSES does not recognize an "end of file" condition on a sequential file.

REV NO: REV 509.029
DATE: August 30, 1999 Discovered By: Jad
Description Of Problem

If hydr_sum is run with a lot of periods and headings on a Windows Machine, it will abort with a floating point overflow.

REV NO: REV 509.032
DATE: September 07, 1999 Discovered By: R. Nachlinger

MOSES get confused sometimes when one only selects some parts of a problem with multiple bodies and he is computing loads. It is possible to loose all of the applies nodal loads for a part.

REV NO: REV 509.033
DATE: January 12, 2015 Discovered By: R. Nachlinger
Description Of Problem

Several more changes to get MOSES running on Linux on Alpha. These have to do with the window interface.

REV NO: REV 509.034
DATE: September 13, 1999 Discovered By: R. Nachlinger
Description Of Problem

This is another set of changes because of Linux on an Alpha. Basically, it does not like to do frequency domain or complex arithmetic. These changes speed things up a lot on an Alpha and a little on other machines.

REV NO: REV 509.045
DATE: December 13, 1999 Discovered By: R.Nachlinger
Description Of Problem

The previous fix "breaks" g_press for bodies which have non zero yaw when the command is issued.

REV NO: REV 509.046
DATE: December 14, 1999 Discovered By: R.Nachlinger
Description Of Problem

The previous fix did not completely solve the problem of using a large number of frequencies and headings when computing pressures.

REV NO: REV 509.047
DATE: December 20, 1999 Discovered By: Smit

Description Of Problem

If one stores and event, then defines connections, and then asks for connector status, MOSES will given an error message.

Using an "open valve" may produce incorrect results if the body has been "moved" with a &describe part -move command.

REV NO: REV 509.052
DATE: February 22, 2000 Discovered By: John Windus
Description Of Problem

If one uses the "MUDMAT" command in the connector design menu for a tripod, he may get a zero divide.

REV NO: REV 509.053

REV NO: REV 509.055
DATE: March 29, 2000 Discovered By: John Wethered

DATE: March 29, 2000 Discovered By: R. Nachlinger
Description Of Problem

In the &SURFACE menu, if one performs certain differences and a panel has a hole in it, then the resulting block will not be closed.
