Long Description

Kolemen Group Automatic & Real Time Kinetic EFIT Project CAKE (Consistent Automatic Kinetic Equilibria) module for OMFIT

The CAKE module is part of the Kolemen Group’s project to ultimately create an algorithm to perform kinetic equilibrium reconstruction in real time. This module serves as a test bed for developing the logic that will convert diagnostic data into constraints that can be placed in the EFIT k-files.

To get started, open the CAKE GUI by double clicking on CAKE. Select the shot and times you are interested in and then press GO. Because the goal of this project is to produce fully automatic data processing and EFITting, it SHOULD just work. But because this project is not fully developed, it might not. So, a developer interface is provided where settings may be changed to attempt to get a better result.

If this software is used in your research, please give appropriate attribution/ acknowledgement/reference to E. Kolemen, D. Eldon, M. A. Roelofs, and W. J. Eggert.
