 If you don't own a copy of the software, you may attend the training class, and receive a 30-day fully-working evaluation copy.



Instructions will be provided by our hull form design expert Steve Toby (703 933 6673). The last training session, a beginner-intermediate course, was successfully held from November 17 to 19, 2009. Another session is planned for the next spring or summer if there is enough demand. At the same time, we are developing an intermediate-advanced course should there be any interest. The outline for the beginner-intermediate course can be downloaded from here.



Instructions will be provided by Dr. Changben Jiang, the developer of VisualSMP. The class is normally held in Alion's office in Alexandria, VA. Tuition depends on the class size. Individual lessons and sessions on cutomer's site are also possible.

The most recent training session was held in Banglore, India, from August 21 to August 24, 2012.  The previous session was completed on March 31, 2011 at Alion's office in Alexandria, VA.

If you are potentially interested in attending, please call Changben Jiang at (703) 933 6612 or Russ Krull (703 933 6812, rkrull@alionscience.com).  Your response is for planning purposes and is not a commitment.   You will receive a follow-up registration package, and may make your formal commitment at that stage.
