Application of large-scale CFD flowfield visualization analysis system

  • 摘要: 设计了大规模计算流体动力学(CFD)流场可视化分析系统(FVAS),系统具有完善而实用的大规模三维定常和非定常流场数据预处理与特征提取、体绘制、几何图形(流线、等值面等)绘制、纹理绘制等功能,并提供多种数据分析手段和良好的交互方法.通过8种展示方式、3种显示模式以及5种视图类型展示流场数据内外流结构特征及其复杂的物理现象.同时系统针对时变数据提供动画展示功能并支持单机多核并行.案例分析表明该系统简单实用,通用性高,多种混合绘制技术能够有效展现燃烧室、进气道等流场数据内部反应情况,切面、剖分等交互方式多视图显示局部细节特征,并通过图表、曲线图等分析工具统计分析具体网格单元的信息.完成测试案例300例,与传统CFD软件相比提升70%以上的绘制效率,系统故障率为0.6%,功能事务成功率100%,有效加速对流场数据的分析统计过程.
