リリースノート(T3D Rev395)

2026/04/29
==========
Revision : 395
Session File Version : 2.5700|0.1360
Transmission3D SDF Version : 0.1360
Build Date : 2026/04/23
Source Revision : 10601
Release Notes:

This is primarily a bug fix release, in order to
address issue (1) below, created by the previous
release (Rev 393). This issue could potentially
crash existing models. If your models do not encounter
this problem, you can skip this release.

The dependencies installer T3DDependencies is unchanged.

1) Bug Fix: A memory allocation bug was introduced in Release 393
(Src Rev 10371, Oct 23 2025), in the PENTA element. This bug was
trying to allocate memory for an array that had already
been allocated. This bug would cause calyx to crash during
the analysis stage.

2) Added to the bevel pinion model, a COMPOUND clearance pin
connection option. This will allow to model multiple
clearance-pin connections for imported carriers
with bevel pinions. Without this new option, the cross-pin
can connect to the carrier only at a single 'hole'
location.

3) Added a new inspection file format option "GDE_XML". Added
GUI options to support the new file format.

4) Added a checkbox in the iSys TOOTH/Utilities menu
to load tooth dimensions from a GDE_XML file.

5) Added new script Scripts/SunModfnMap.cmd, which creates
a data file which can be used to create a Surface
pot of total surface modification vs Roll and FaceWidth,
for a Sun gear.

6) Added new script Scripts/postsplinecontactresults.txt to
extract contact result data for a detailed spline (Conformal
Sun-Ring) contact pair.

7) Relaxed the 45 Degree max limit on the CupAngle in a tapered
roller bearing. Now we allow it to go all the way to
90 Degrees.

8) Curvic couplings: The WholeDepth and ChamferDepth should be
measured perpendicular to the EndAngle,not along the length
of the flank.

9) In the Curvic Coupling CUTTER menu, the POINTWIDTH parameter
is not used. So it has been removed.

10) Enabled a new MKL based eigen solver for dynamic analysis.
For Static and Quasi-static analysis, we continue to use the
old eigenvalue solver, which is slower, but significantly
more precise.

11)The Curvic Coupling calculation of the location of the
thickness measurement point (rthick,zthick) has been
corrected so that it works correctly, even when the Pitch
cone is very close to the Face cone.

12)Fixed the Curvic coupling mesh generator so that it works
for all combinations of CONCAVE/CONVAX and signs of the
HorizontalSetting.

13)Fixed the problem where sometimes Rotor races would not
assemble together correctly if a Sun, Ring or similar
race coincided simultaneously with more than one mutually
non-contiguous rotor races.

14)Bug fix: vGlass would crash when the attribute of the
contact pattern was changed.

15)Fixed typos in the help messages for MAGLOGMOD and
LEFFLOGMOD for the various bearing types.

16)Fixed bug in iSys where incorrect value was being set
for FourPointBallBearing ContactAngle1 when bearing was
displayed. This bug only affected the 3D display in iSys.
The model generated for analysis was correct.

17)In iSys, the NAME of a pinion bearing was not being
shown on the Model Tree. This is now corrected.

18) Bug Fix: The straight bevel mesh generator crashed
on Linux when built using the clang based compiler suite.

リリースノート(T3D Rev394)

2026/02/25
==========
Session File Version : 2.5700|0.1357
Transmission3D SDF Version : 0.1357
Build Date : 2026/02/23
Source Revision : 10520
Release Notes:

This is primarily a bug fix release, in order to
address issue 10) below, created by the previous release (Rev 393).
This issue could potentially crash existing models.
The dependencies installer T3DDependencies is unchanged.

1) Added in vGlass, a new option for the coloring based on either
the Rigid body component of displacement, the FE component, or
the total (FE+Rigid) displacement. Previously only the FE component
was used by default when coloring the meshes. There are new checkboxes
in the Attributes menu that show up when the DISPLACEMENT attribute
is selected, to allow the user to pick which combination
of FE and Rigid deflections should be used to color the meshes.
Also added the Rigid and Total components of displacement to the
Pick tab in vGlass.

2) Modified vGlass such that the "Logarithmic Scale" checkbox also
applies to the length of the arrows used for 3D vector
attributes.

3) Allow crossed rotor axis for SUN_SUN and SUN_RING pairs.

4) Allow negative clearance at CLEARANCE_PIN_CARRIER interface
for bevel pinions. This allows modeling of a press-fit condition
between the cross pin and siff cage in a differential.

5) Bug Fix: iSys was crashing when loading pointcloud with partial slice
information.

6) Bug Fix: Fixed multyx crash during GENERATE for certain
Straight-Bevel models when SegLen() became zero between
two points in the straight bevel mesh generator.

7) Bug Fix: Fixed multyx crash issue when running it
from the Command Prompt due to incorrect Index Array of SDF variables.

8) Bug Fix: When we apply a non-zero DELTA_TEMPERATURE to
a model with a straight bevel differential and with a clearance
condition at the hole between the cross-pin and the diff-cage,
the model was crashing calyx.

9) Bug Fix: Incorrect index of the critical point passed in SUB_SURFACE menu.
The first argument iCandCrit, sent by the SUB_SURFACE menu to the calyx
function Output_Subsurface_Stress() was off by one.
Output_Subsurface_Stress() needs a 1-based index, while a zero-based
index was being sent.This bug crashed calyx when running tyhe
SUB_SURFACE menu in a few cases.

10)Bug fix: Incorrect clearance value accessed to calculate
pitch radius of ball and spherical bearing. This was crashing
calyx. This was due to the new flag BALL_CLEARANCETYPE_ROLLERPINIONBRG
introduced in Rev 393 to fix bearing clearance definition.

11)Fixed a bug in the script file Find_Pattern_Results_At_RZ_Values.cmd
