Abstract:

The one-dimensional Lagrangian hydrodynamics computer program PUFF is described. The code is used primarily in the study of X-ray effects and uses finite difference methods to solve the equations of hydrodynamics using slab geometry and assuming 1-dimensional flow through a 1-centimeter-square pipe. The original PUFF was a derivative of a code of the Lawrence Radiation Laboratory O. Nance, M. Wilkins, I. Blandord, and H. Smith, Sharp, A one- dimensional hydrodynamics code for the IBM 704, UCRL-5206-T, 1958. PUFF is now used to refer to an energy deposition code, while P PUFF refers to a plate slap or flyer plate code. The two codes are essentially the same except for the generator subroutines. The report explains the major calculations in each subroutine and describes all inputoutput variables. The subroutines are for the generator, rezoning, editing, equation of state, and input variables. Sample problems with the appropriate data deck are included to allow a user to become familiar with data arrangement and to check the program on his computer. The appendixes include FORTRAN listings of the 2 codes.
