java.lang.Object

+ssfd.ExpTauE
 public class ExpTauE
 extends Object
Uses a standard power law expression for the energy confinement time.
The exponents are specified at instantiation. The resulting
expression can then be evaluated for when a set of global plasma
parameters is provided.
There is also a
User's Manual for the
fullfeatured FORTRAN code upon which this code is based.
The corresponding equation numbers are mentioned in the code below.
