6) How to setup new problem
Version 3 Created by Jonathan M. on 05 Feb 2013. Previous Version
1) For example, copy existing problem to new problem code.  Start in HARM directory tree and do:

cd initboundcode
cp init.fishmon.c init.subkep.c
cp init.fishmon.h init.subkep.h
cp bounds.fishmon.c bounds.subkep.c

2) Edit the new files.  For changes in physics, focus on init.subkep.c .  Look for the function init_dsandvels() to setup the initial density, u, v^i, and B^i.  Look for init_vpot_user() and change the initial vector potential.

Note that for the fishmon code that $GM=c=1$.

3) Can add new problem by adding another WHICHPROBLEM type.  Do this by introducing a new problem type (e.g.):

#define SUBKEP 3

4) Change #define WHICHPROBLEM to:

#define WHICHPROBLEM SUBKEP

5) Anywhere you see "WHICHPROBLEM" identify if you want to do something new or just repeat the prior problem setup (e.g. just add ||WHICHPROBLEM==SUBKEP).

6) 

3) Redo the soft links to init.c, init.h, and bounds.c:

cd ..
rm -rf init.c init.h bounds.c
ln -s initboundcode/init.subkep.c init.c
ln -s initboundcode/init.subkep.h init.h
ln -s initboundcode/bounds.subkep.c bounds.c

4) Now follow directions in Quick Start Guide: Notebook #1 to compile and run code.
