摘要
针对结构分析软件面向多物理场的应用,分析讨论面向对象有限元并行计算框架PANDA的多物理场耦合服务设计,即多物理场分析类型的扩充能力、不同物理场间的数据传递和多物理场耦合分析的求解策略.在PANDA提供的多物理场耦合服务的基础上,开展热-力耦合分析功能的程序开发,实现热弹性分析功能.热弹性分析算例计算结果与ANSYS的计算结果完全一致,表明基于PANDA框架的多物理场耦合功能开发已取得一定进展.
As to multiphysics-oriented application of structure analysis software,the multiphysics coupling service deign of object-oriented finite element parallel computation framework PANDA,i.e.multiphysics analysis function extensibility,data transfer among different physics fields and multiphysics coupling analysis strategy are analyzed and discussed.Based on the multiphysics coupling service of PANDA,thermal-mechanical coupling program is developed and thermoelastic analysis function is implemented.The result of thermoelastic analysis based on PANDA is exactly the same as corresponding result obtained by ANSYS.It is shown that the development on multiphysics coupling function of PANDA achieves some progress.
