Simulation still useful

Postby CherryPick » Tue Jun 16, 2009 2:45 pm

Hi everyone

I have been reading the forum for a year by now, but I just registered now, because it is required if you want to write something.

I think that simulating Polywell is useful even when it uses approximations.
Someone have even started . See the bottom part of the page.

The first reason to write a simulation is promotion. Visualization of the behavior of the Polywell helps laymen like investors and politics to understand it. The effort of creating a good enough model is not huge. Is someone working with ephi ?

The second reason to write a simulation is the evaluation of design parameters like sizes, geometries, field strengths, etc. Building a WB-X takes months, even years, but a good simulator can evaluate thousands of options in that time. The armies don't do nuclear tests anymore, because they can do the tests using computers. Of course, they have calibrated the model by real bomb experiments. In the case of Polywell, to create a good simulator, you need to have a lot of experimental measurement data. I assume that the current project creates a lot of data. BTW, where do they use the fast speed camera.

I agree that creating a real life Polywell is the most urgent thing to do. If it works, accelerating the designs by software simulations can be considered. If WB8 does not work, then simulations could be the only affordable way to find out why not?

In theory there is no difference between theory and practice, but in practice there is.

Came across a description of the simmulation code used by Bussard circa 1992.
