GE FULL PROBLEM (with diff. num. particles)
The following runs use the original XPDC1 cross-sectional data.
All the runs were conducted on the Cray T3E MPP machine in
batch mode using the parallel version of XPDC1.
We used 16 processors for the 400 K particle runs.
All the other runs used 64 processors.
The simulation starts off with initial Bessel function
electron and ion density profiles with axial density = 1.0e11/cc.
The number of particles in the simulation is varied by changing
the parameter nc2p (ratio of number of real particles vs. computer
particles). For 400 K particles, nc2p = 5.0e7.
The following is a link to the input file for 400 K particles:

The simulations were run for 3.6 microseconds.
The following is the result of doubling the time step in
the 400 K particle run. This simulation was run for
2.2 microsecs. Doubling the time step does not reduce
the heating at the axis. Instead the axial peak growth
rate increases.
