MULTI — A computer code for one-dimensional multigroup radiation hydrodynamics

Abstract
The basic physical equations as well as a computer code for the simulation of one-dimensional radiation hydrodynamics are described. The hydrodynamic equations are combined with a multigroup method for the radiation transport. The code, written in standard FORTRAN-77, is characterized by one-dimensional planar geometry with multilayer structure. A time-splitting schema has been adopted with implicit finite-differencing formulation (including the hydrodynamics), and Lagrangian coordinates. Tab...

Title of program: MULTI
Catalogue Id: ABBV_v1_0

Nature of problem
In inertial confinement fusion and related experiments with lasers and particle beams energy transport by thermal radiation becomes important. Under these conditions, the radiation field strongly interacts with the hydrodynamic motion through frequency-dependent emission and absorption processes.

问题特性
在惯性约束聚变及相关的激光、粒子束实验中，热辐射输运过程发挥着关键作用。在此类工况下，辐射场会通过频率依赖的发射与吸收过程，与流体动力学运动产生强烈的耦合相互作用。
