[FLASH-USERS] Adding new particle attributes to be written to the particles output file

[Anshu Dubey]

Nathan,

You should include the following lines in your application config file


   PARTICLETYPE newtype INITMETHOD lattice MAPMETHOD quadratic
ADVMETHOD rungekutta

   REQUIRES Particles/ParticlesMain
   REQUESTS Particles/ParticlesMapping/Quadratic
   REQUESTS Particles/ParticlesInitialization/Lattice
   REQUESTS IO/IOMain/
   REQUESTS IO/IOParticles

If you have a new way of initializing, or mapping, you have to specify
those in the
first line and request appropriate subunits. Basically the first line registers
your particle type with the framework and the REQUESTS lines make sure that the
appropriate subunits are included.

If you need further help with this please write directly to me.

Best,
Anshu
