ADINA System 9.2.3

ADINA System 9.2.3
This section lists the new and updated features that are available in ADINA System
9.2, as
com
pared with ADINA System 9.1.3
. (For features and improvemen
ts added between 9.2 and
9.2.3, see the section “Improvements between 9.2.0 and 9.2.3” b
elow.)
There are new commands and new and changed parameters associate
d with the new and
updated features. The release not
es refer to the commands and p
arameters in the command-
line formats. Further informati
on about the new commands and new and changed parameters
can be found in the AUI Command Reference Manuals.
For user interface users, most
command-line parameters have analogous fields in the dialog
boxes.
Note, when we refer to documentation, we refer to the versions of the documentation given
below in the “Available Documentation” section.

ADINA System 9.2 Release Notes
AVX extensions
Recent Intel and AMD CPUs suppor
t the AVX (advanced vector exte
nsions) instructions in
the x86_64 instruction set. The ADINA 9.2 executables for the
solvers (ADINA Structures,
ADINA Thermal, ADINA CFD/EM, ADINA FSI, ADINA TMC) now use the
AVX
extensions, as described below.
Depending upon the computer and th
e problem to be solved, the executables that use the AVX
extension can run up to 30% more
quickly than executables that
don’t use the AVX extension.
Linux versions
One way to check to see if a c
omputer supports AVX is to search
for the string “
avx
” within
the file
/proc/cpuinfo
. If the string is not found, t
he computer does not support the AVX
extensions; if the string is
found, the computer supports the A
VX extensions.
Two versions of the ADINA executa
bles are supplied, one version that does not use the AVX
extensions, and one version that uses the AVX extensions. Duri
ng installation, if the
computer supports AVX, the AVX ve
rsion is installed by default,
and if the computer does
not support AVX, the non-AVX version installed by default. You can override the defaults
during installation.
At run-time, the ADINA command scripts check to see if the AVX
extensions are supported
on the computer. If the AVX exte
nsions are not supported, the n
on-AVX executables are
automatically used by default, a
nd if the AVX extensions are supported, the AVX executables
are automatically used by default.
If a computer supports the AVX extension, and you do not want t
o use the AVX executables,
use the
-noavx
flag, for example
adina9.2 -noavx …
If the solver program
is run th
rough the user interface (either through the AUI or using the
ai9.2
script), a check button is available in the Settings window to run the non-AVX version
on a computer that supports AVX.
Windows versions
The installation package contains both the AVX and non-AVX vers
ions. During installation,
the computer is checked to see if AVX is supported. If AVX is s
upported, the AVX version is
installed. Otherwise, the non-AVX version is installed.

Improvements to low-speed dynamics
The program
can now autom
atically
switch to low-speed dynamics
at no convergence, for
specific element groups.
The low-speed dynamics inertia f
actor (LSMASSF) can now be grea
ter than 1.

Improvements to energy calculations
The following improvements are
made to energy calculations:
The out-of-core solver is now supported.
Contact compliance energy is improved.
Contact damping energy is improved.
Improvements to 3D plane stress element
The 3D plane stress element (membrane element) can now be initi
ally warped.
Improvements to mesh glueing
The gluing constraint functions a
re changed slightly when there
are several glued surfaces that
intersect. 3D plane stress elemen
ts can be used in the glueing
of 3D surfaces.
Change to u/p formulation defaults
The default number of pressure d
egrees of freedom used in the u
/p formulation is changed for
the following elements:
2D plane strain and axisymmetric element:
5 to 8-node quadrilaterial eleme
nt and the 6-node triangular element: Default number of
pressure degrees of freedom is changed from 1 to 3.
3D solid element:
9 to 21-node hexahedral or prismatic element, and the 10-node t
etrahedral element:
Default number of pressure degr
ees of freedom is changed from 1 to 4.
This change is made to make the elements stiffer. The defaults
in version 9.1 correspond to
elements that are
