No rating yet Subject: XANS: 5.4 problems with Sun 2.6 OS Author: Don Shaffer Date: 1999-01-07 16:15:00Thanks for the many suggestions on the problems discussed so far with ANSYS 5.4 on Sun 2.6. I have received a list provided by our ASD of recommended patches. After checking the list It was reported that we have all these installed to at least the patch revision level suggested or above.
But, Still seeing same kinds of problems; these kinds of errors:
bus error segmentation faults arithmetic exception
The problems seem to occur after a plotting command has been issued from the GUI. Also have noticed a dramatic increase in the time to prepare a screenplot, many times, the plotting task completion bar quickly goes all the way to the end yet the plot never appears until after an indeterminate delay. Sometimes when it does finish, recently generated geometry is missing from the plot. A command "plot lines", or "multi-plot" must be reissued from GUI in order to get geometry to show up correctly. Does the software control the screen plot-paging, or does the OS control this function [does anyone know].
We have found that the CDE seems to offer less crashes then the Open Windows Environment. Also seems like the 3D graphic driver does better than the X11, or X11C. But the 3D driver has another problem with graphic display window not correctly repainting after a message window covers a portion of the display.
Would like to continue discussion on this thread. Dan Bolen had sent message that these are old problems, but suggestions by our ASD has not fixed the problems yet. Also another message about single cpu version instead of multi cpu version, I thought this was only applicable to new version running 5.5.1 on old Sun OS 2.5.x.
We have contacted ASD/Ansys with problem reports and trace backs that appeared in POST1; again these seem to be occurring when some plotting is requested. I do not know if the problem has yet been isolated to only one of the software participants; i.e. 2.6 OS, Ansys, or License Man.
