To run the torus code:
Compile with: tcbuild --optimize --cc-flags "-O2 -I./ib/util -I./ib/fluid -I./ib/interact" ib/main/IbMain.ti
Have these input files: fibers and markers
The code will run 8 timesteps, and output performance numbers as well as writing out output files.
You could also convert the fibers input file from the ASCII version using the Pc2jpc program yourself.
