Codes LSP and OSIRIS
OSIRIS (developed at UCLA) Explicit PIC
LSP (product of MRC Albuquerque) Explicit or
Implicit Particle (PIC) or Fluid

• Courant condition for the electromagnetic fields
  ?tlt?x/c
• Numerical heating if ?xgt3?D

• Courant condition is unnecessary in the implicit
  mode, non-resolved temporary modes are damped,
  remaining limitation ?t lt ?x/vte
• Implicit PIC
• numerical heating or cooling if ?xgt?D
• Implicit fluid
• no numerical heating or cooling
