辐射流体力学RH2D程序的重构与改进
Reconstruction and Improvement of the Radiation Hydrodynamics Code RH2D
摘要
Abstract
In scientific computing and industrial applications, some programs integrated with physical models and numerical methods and verified by theories and the experiment in the past long time, have much more confidence in numerical simulation. But these programs are not suitable for the research requirements in numerical accuracy and computing scales at present. In this paper, the code RH2D have been reconstructed based on JASMIN, and the radiation heat conduction numerical method has been improved from the splitting method to the non-splitting method. The numerical results for practical problems are presented to show that the non-splitting method has smaller energy conservation errors and much higher parallel efficiency than the splitting method.关键词
