APPENDIX C. GUIDE TO RTD SIMULATION CODE 148<br />
henry2 maintained by the High Performance Computing division at North Carolina<br />
State University. The newcompilehopf is tuned for a particular version of Trilinos,<br />
and therefore, must be editted with that in mind. Here are the steps for performing<br />
a continuation run through a voltage range for the RTD simulation.<br />
1. Set parameter values in grid.h and material.dat.<br />
The values set in grid.h determine the discretization and correlation length used<br />
in the simulation while the values set in material.dat determine the physical<br />
structure of the device.<br />
2. Copy makeinit to makefile, typemake clean, typemake, and run the compiled<br />
program init.<br />
Typing make clean will clean up remaining files from previous initializations,<br />
and typing make compiles the program init. Run the program by submitting a<br />
job to the queue.<br />
3. Set the continuation parameters in RTDContinuationParallel.C and copy the<br />
initial guess for the steady-state distribution at the first continuation parameter<br />
into the data file initial.out.<br />
You will need to set such things as initial voltage parameter, lower and upper<br />
bounds on the voltage range, initial step in the voltage parameter, and decide<br />
if you want to compute eigenvalues for a stability analysis of the steady-state.<br />
If you want to start at V =0,thencopysol.out to initial.out since f0(x, k) is
