Section 4 – Oasys T/HIS: Bugs fixed in version 9.3
• Case 11692 and 11300
In versions of T/HIS prior to 9.3 the Force Magnitude is not extracted correctly for Nodal Force
Groups from the LSDA (binout) binary file. This has been fixed in version 9.3.
• Case 11675
In T/HIS 9.3 RC1 and RC2 some thick line styles were not drawn correctly when images were
output at 2 and 4 times the screen resolution. This problem was machine dependent and occurred
if the line width was greater than the maximum line width supported by the version of OpenGL.
This problem has been fixed in T/HIS 9.3 by drawing lines that are thicker than the maximum line
width supported as a series of rectangles.
• Case 11672
In T/HIS 9.3 RC1 and RC2 thick lines were sometimes not displayed correctly on the screen if the
curve contained a large number of points in a very small area and would appear as though they
had small gaps in the curves. This has been fixed in 9.3.
• Case 11670
In versions of T/HIS prior to 9.3 the wrong point was updated in the list of curve points when a point
was edited by dragging it interactively. The correct point in the curve was updated it was just the
feedback that updated the wrong point. This has been fixed in version 9.3.
• Case 11664
In versions of T/HIS prior to 9.3 FAST-TCF scripts generated an error if they used the option to
extract the Y value at a given X (yatx) and they were played more than once. This has been fixed
in 9.3.
• Case 11658
In T/HIS 93RC1 and 93RC2 the Seismic/FFT function only worked the 1st time the menu was
displayed. After that the following error message was displayed.
'THMATHS: Unknown function code, contact Oasys'
This has been fixed in 9.3.
• Case 11581
In versions of T/HIS prior to 9.3 the list of curve files returned using the option to select multiple
files on a PC was in an order controlled by the PC file selector. In version 9.3 onwards the files are
sorted into alphabetical order before they are read.
• Case 11489
In versions of T/HIS prior to 9.3 the option ot search directories recursively could get stuck in a loop
if the directory structure being searched contained a circular loop using logical links. Version 9.3
has has been modified so that each directory is only processed once even if a loop exists within
the directory structure. This problem would only affect UNIX/LINUX versions as Windows does not
support the concept of logical links with native NTFS file systems and Windows versions of the
software would not follow logical links on NFS mounted file systems.
This fix has also been applied to the option in D3PLOT to search directories.
• Case 11464
In T/HIS 9.3 RC2 T/HIS could apply the wrong label to curves if multiple contact forces were read
from the LSDA file in one go. This would only occur if the contacts in the RCFORC file were not
sorted into increasing ID order. If the force from a single contact was read then the labels would be
correct.
• Case 11401
In versions of T/HIS prior to 9.3 T/HIS would not read the data correctly from THF and XTF files if
you had a file that was larger than 2GB.
If you had a THF that was >2GB and then a THF01 file that was < 2GB then T/HIS would use the
size of the THF01 file as the family member size and would therefore skip the data at the end of the
THF file. This has been fixed in 9.3.
