MCNP has needed a graphics interface for a long time.  The Visual Editor provides this interface, and much, much, more.  The code displays geometry, of course, but can also be used to create geometry and display 3-D depictions of modeled objects with various color schemes.  These features make the code and the training provided by the class essential to anyone who has wondered if an MCNP input file depicted the problem geometry accurately, assigned the materials to the right cells, and placed the sources properly.  In addition, the code can plot tallies, and can plot points where source particles are created, where collisions occur, and where interactions that contribute to tallies take place.  Such plots reveal phenomena like radiation streaming, and show which parts of the model contribute to tallies.

Every MCNP user should acquire the Visual Editor and participate in the Visual Editor Consultants class.  The gains in analytical power and productivity will far out weight the expenditure of time and money.

I believe this is a great course for users at any level.  I had never used the Visual Editor or MCNP before the class but the curriculum is so thorough and so well laid out that I was able to keep up with users with many years of experience, who also expressed considerable satisfaction with the class.  The best part is that the class can be taken again and again after you leave using the supplied manuals, exercises, and software.  The tools from the class become a valuable resource for general use of the Visual Editor and MCNP.  It was probably the best week I have ever spent learning anything associated with the nuclear industry.

First of all, Randy is definitely the type of person you will want to learn from for a class like this. His personality and teaching method ensure that you are going to fully understand what you are doing and catch on quickly. Second, the power of the visual editor is unbelievable. With what I have learned, I can safely say that I no longer consider code creation to be of a comparable time length to problem setup and output analysis.

The Visual Editor provides tools for creating complex geometries rather easily and includes error checking and 2-D and 3-D visualization to assist in the interpretation. When you look at the code that is generated you can only wonder as to how it would be possible to do this otherwise and how you could ever validate that what you have is what you want or is correct.

VISED is an exceptional tool for both novice and experienced users. This class offered me the opportunity to explore its full capabilities - as both a geometry generator and a visualization tool.

The class was definitely very useful to me, and I would recommend it to all users and developers of MCNP. It helped produce input files for MCNP much faster and easier, and probably even more important, the visualization provided by the Visual Editor helps me understand much better the results and the physics of the simulated problem.
