DESCRIPTION:



Execution of the STIFFNESS ANALYSIS command or the static analysis split

solver commands will abort due to division by zero for models containing

plane curved elements (type = PCURV) under the following conditions:



     1.   Member loads are defined for the element(s).



     2.   Element properties for the plane curved elements are defined

          using the section property specifications and giving values for

          AX and IZ only.



Workarounds:   Workarounds for the problem include specification of an

               arbitrary value for the IX section property or using the

               TABLE option for the specification of the curved element

               properties.

                                             DATE: January 5, 1996



DESCRIPTION:



     The SOLVE FOR FATIGUE command will not execute to completion and

compute joint displacements if preceded by an eigenvalue analysis.  This

will not be evident until a COMPUTE FATIGUE command is given, in which

case the following error message will be printed:



     ****ERROR_STFCHK -- COMPUTE FATIGUE RESULTS NOT

                         POSSIBLE.  FATIGUE SOLVE NOT YET

                         PERFORMED.



Workaround:    eigenvalue analysis results are not needed in the same job

               that performs a fatigue analysis which includes the SOLVE

               FOR FATIGUE and COMPUTE FATIGUE commands.  Therefore,

               perform the eigenvalue analysis and fatigue analysis in

               separate jobs.  Furthermore, do not perform a fatigue

               analysis in a job that restores a save file that contains

               the results of an eigenvalue analysis.  If the eigenvalue

               analysis and the fatigue analysis use the same structural

               model, use the same sequence of commands that define the

               model (JOINT COORDINATES, MEMBER INCIDENCES, MEMBER

               PROPERTIES, etc.) in both the eigenvalue analysis job and

               the fatigue analysis job.
