Example Problem: Submitting batch job to compute
animations showing the influence of elastic anisotropy on
two-dimensional wave propagation in a unidirectional graphite/
epoxy plate under the conditions of plane-stress / -strain
The FEM model is a small mesh (30x60)

Instructions for using this form:

    1. Enter appropriate numbers in the boxes,
    2. enter your email address,
    3. click on submit, and
    4. wait for results to be returned to your email. (this will take about 15 minutes)

  1. You can either select web links in the email or view the results directly by going to the directory
    http://www.jwave.vt.edu/output/wave2d_30x60_ "unique date-time"/. If your email does not provide direct web links, copy and paste the web address from the email into your web browser location window.
  2. All results are organized in one file:
    http://www.jwave.rkriz.net/output/wave2d_30x60_"unique date-time" /results.html
    If the form is submitted "as-is" you can view the simulation results as an animation.
  3. You should check the files wave2d_30x60.out to verify that the job ran correctly.
  4. You can also download files from your web browser to your computer for archiving. If you are in the SMVC we will provide a 4.6Gbyte read/write optical disk for each student so that they can store their large simulation files. NOTE: ALL FILES WILL BE DELETED AFTER 3 DAYS.

    Here are some images with back-ground-info that describes this problem in more detail.

    BULK WAVE PROPAGATION SIMULATION IN UNIDIRECTIONAL Gr/Ep
    -----------------------------------------------------------
    Unlike isotropic materials waves propating in anisortropic materials deviate from
    the wave normal ni. This anisotropy quides the wave energy propagation shown in
    the animations provided above. From this simulation new relationships can be      
    seen: 1) the faster moving QL wave has a longer wavelength, 2) diffractions         
    from reflected bulk waves create Rayleigh surface waves, 3) the reflected QL       
    wave energy propagates back towards the origin, 4) this refection does not             
    generate another bifrucation of energy into yet another QL & QT wave. This        
    information suggested that waves could be launched preferentially
