Run ABAQUS jobs on Cray in /tmp

Cray /tmp is cleared every hour of files 24 hours old

To run the abaqus job:

    abaqus58 job=namewithoutinp que=<express, huge, or large, etc>

To convert .sel to .fil file:

    abaqus58 job=namewithoutinp que=<express, huge, or large, etc> convert=select

    convert = select translates .sel file to .fil to allow us to bring it into hypermesh

My preferred SI unit system:
 

**Using units of:
**
** mm    == length
** N == force
** N mm == torque
** MPa   == stress
** mass  == 10^3 kg (tonne)
** velocity == mm/sec
** acceleration == mm/sec^2
** density == 10^3 kg / mm^3
** engery == mJ  (milli-Joule)
**
** To convert density units from g/cc
** multiply by 1e-9
** to get 10^3 kg/mm^3
**
**
*Material, Name = steel
*density
7.827e-9
*elastic
207.8e3, 0.3

My preferred inch-pound-second unit system:
 

**Using units of:
**
** in    == length
** lb  == force
** lb in == torque
** psi   == stress
** mass  ==
** velocity == in/sec
** acceleration == in/sec^2
** density == 10^3 kg / mm^3

** gravity = 386 in/sec^2
**
** To convert density units from lb/in^3
** multiply by 12 then divide by 386
**
**
**
*Material, Name = steel
*density
7.351e-4
*elastic
30.0e6, 0.3
 
 
 
 


To create a flattened ABAQUS input file (no part or assembly definitions)
put the following line in the environment file:

cae_no_parts_input_file=ON

I find that a flattened file is more readable and can be edited by
hand easier than the usual CAE written input file.


When to use OP=new on the *CLOAD card:
***see caution when using amplitude card!!!

*************using a time history of evenly spaced data
******************first, define an amplitude card
*Amplitude, name=loadramp, definition=EQUALLY SPACED, fixed interval=1.
0.0, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0
*******the fixed interval is the time between loads.  Here, there are 7 loads.

***********within the step, define direct analysis so that it uses every point in the
***********history.  Best use this option when you are working with linear elastic analysis,
***********or you are comfortable specifying your own increments instead of relying on the
***********auto incrementation scheme.
*Step, direct
1.0, 7.0
***********1.0 is the time interval, same as defined in the amplitude card
***********7.0 is the total time of the step, e.g. interval*loads in history = 7.0
 

*cload, op=new, amplitude=loadramp
top, 1, -4448.2216
********************uses loadramp amplitude card, applies load to node set "top" in the 1-direction
********************and modifies the value by the multiplier -4448.2216.
********************this example essentially applied Kips to a model defined in Newtons
********************i.e. time point 3 is 1.0 kip so 1.0*(-4448.2216) Newtons are applied

******CAUTION********I have had cases where I used OP=New with a defined *CLOAD amplitude,
******where it appears as if the load was still carried over from the previous step.
******therefore, it may be best just to set the previously defined load equal to zero, e.g.

*cload, op=new, amplitude=loadramp
top, 2, -4448.2216
top, 1, 0.0

Problem:  On a multi-core processor, i.e. quad core or a dual core, abaqus will not optimize computor performance. It thinks one core
               is one computer. On a quad core, your PC will run Abaqus at max 25%. Or on a dual core, it will max at 50%.

Solution:   To run a simulation on more than one core, add the following line in the command widow " CPUS = 2".

                 Example:            C:\[your working directory]> abaqus j=jobname cpus=2

                 This example will run a quad core processor at 50% OR a dual core processor at 100%.

                 To run on three cores, then "CPUS=3" and so on...

Windows 2000 Backup and HP Tapedrive
Backup procedure using tape drive:
-turn on tape drive
-insert blank media
-reboot computer
-go to lunch
-start windows backup
-verify options for normal backup--normal backup may exclude some files
 

Graduate Students and Data Security
Your data files from tests and document files related to papers are your
most valuable assets.  As a graduate student, you will be required to
make sure you data is secure and archived.

Each graduate student will be issued an external hard drive.  This hard drive
is to be used for backup purposes only.  Software is available for
automatically copying files to this backup location.

Data files should be backed up daily.  Other files should be backup at
least once per week.  Once per semester, your external hard drive
should be taken to Dr. Barkey and backed up with the tape drive.

DO NOT use the external hard drive for regular file storage.  Only
use this for backup purposes.

Hard drive failure is an eventual certainty--it's not a matter of "if" it
will fail, but "when".
 
 
 



Setting up HyperMesh on a PC with Windows 2000:
 

    IMPORTANT:  Give explicit permission for each user to have FULL CONTROL on the
    event log and event log backup files:

        d:\altair\security\hwlog.bak
        d:\altair\security\hwlog.dat

    which are created after the first time Hypermesh is run.
 

To import an ABAQUS *.inp file into hypermesh:

    start hypermesh
    file, import, then select the ABAQUS translator, choose the *.inp file, press the import button

To get ABAQUS results into hypermesh, first execute hmabaqus from the command line:

    hmabaqus [options] -cray *.fil *.results *.model
    (hmabaqus [options] -cray <inputfile> <outputfile> <modelfile>

    where * is the ABAQUS fil file.  Note that if an ABAQUS explicit job is done, then the
    *.sel file needs to be converted into a *.fil file first.

    Then, start hypermesh and IMPORT the <modelfile> using the hmascii.exe translator.

    Note: this procedure must be used if *NGEN or *ELGEN cards were used to create the ABAQUS
    input deck (likely to happen for ABAQUS sample files).

To check for duplicate nodes:
    Go in the Tools menu, Edges sub-menu, Equivalence panel.

To make a screen capture:

    Set JPEG quality in Options: Postscript
    use ALT-F6 to make a screen shot

    use POSTSCRIPT to make a postscipt file that can be read into Corel

    files will be located in My Documents
    and name imageX.jpg or postX.eps where X is the next available number

    Alternatively, Corel Capture can be used.
 

To make a circular surface and then mesh it, go to 2d, planes, and select a circle.

Scanning Exams and Solutions

    Using the OneTouch 9220 Scanner, Corel PhotoPaint, Acrobat, Lotus Manuscript:
    Scan in hand drawings into Photopaint at 300 dpi gray-scale.
    convert to 1-bit black and white (line drawing) with a threshold gamma around 200
    export the image as eps

    In manuscript, use a picture marker to bring in the eps file
    print the file to a postscript file (ps)
    use Acrobat Distiller to convert the ps to PDF
 

    Grey-scale or color images can be scanned directly into a PDF at 300 dpi.  If the resulting
    file is too big, print the PDF to the Acrobat printer.  70% percent compression or more can be
    obtained from the resulting PDF compared to the original.

    Handwritten solutions can be scanned into PhotoPaint at 300 dpi, converted to BW line drawing,
    exported as EPS, and finally loaded into Acrobat as 'create PDF from multiple files'
