4.87
R1
Added new licensing
system. To work with the new version 4.87, the process
of updating dongles is fundamentally changing, see the user manual for details. After the
dongle is converted, all previous versions of the program
(4.86 and lower) with this dongle will no longer work. Project
files opened in the new version will be converted to version
4.87. v4.87 files ill not open in older versions (4.86 and
lower), but conversion of such files is possible through neutral format.

In Start-Elements, added consideration
of branch stress in gauge analysis of U-, L- and Z-shaped pipes Added properties of standard
WITZENMANN axial, angular and lateral expansion
joints to expansion joints database Improved input dialogues for
custom restraints
and custom expansion joints.
Friction restraints are now set automatically Gaps can now be inserted for
guiding
supports Changed analysis of guiding supports: 1
- friction is considered along the vertical
plane of lateral supports, as well as the horizontal support
plane; 2 -
lateral restraints and
friction are still in effect when vertical restraints are
disabled. To get results equivalent to old analysis versions,
when opening START-PROF 4.66 or lower version files, guiding
supports can be set to be automatically converted to custom
restraints, according to the old modeling version for guiding
supports. This
change is not reversible - when a single-directional guiding
support is disabled, 4.67 analysis results will always be
different from 4.66 and lower. Added ability to input restraints
with gaps for custom restraints Added pipe element names. More... Switched to Unicode.

When opening a material
or soils file, a dialogue offering to input new elements into
the database pops up. If
the materials or soils in the file are present in the database,
but their properties differ, 3 options are available:
update database properties,
add element to the database
under a new name, or

4.61, 27.06.2008
Added
automatic consideration of pendulum
effect in variable spring hangers
(rod displacement from vertical). START-PROF 4.60 and lower
files set rod length as 0 by default (pendulum effect is not
considered) Added
automatic consideration of friction in variable spring supports.
START-PROF 4.60 and lower files set the friction factor
as 0 by default (friction is not considered) Added
new element - cap.
Using caps allows more accurate modeling of internal
pressure thrust loads on supports and equipment connections.
START-PROF 4.60 and lower files automatically
place caps in all free end nodes (without supports or fittings).
See pressure
thrust force and bourdon effect All
branches are now analyzed
for bending and internal pressure. Branch types are changed
from "bend", "flange", "welded"
to "elbow", "bend", "miter",
"extruded". New properties
are added for branches (number of miter joints, weld quality
factor, presence or absence of flanges, weld position relative
to branch plane). START-PROF 4.60 and lower files use bends
for branches with a radius of less than 2D
and branches with flanges, while branches with a radius of
more than 2D are
changed to bends. Welded branches are replaced by miter branches,
where the number of miter joints is automatically determined
in order that the skew angle is 22.5 or 15 degrees. We
recommend reviewing, and if necessary editing, outdated file
versions. Total
allowance is
change to two parameters for all pipes and fittings
- "corrosion allowance"
and "mill tolerance". START-PROF
4.60 and lower files automatically
set mill tolerance as
10% of wall thickness,
while the rest of total
allowance is taken as corrosion allowance. Mill tolerance and corrosion tolerance combined
always equal total
allowance. We recommend
reviewing, and if necessary editing, outdated file versions. Added
pressure analysis
for miter and extruded
branches using RD
