摘要
从非稳态导热的离散方程出发,根据VonNeumann的格式稳定性判别方法,给出二维导热数值计算显式格式的稳定性条件。由统计热力学的观点对稳定性条件进行分析,认为稳定性条件实际上是物质本身的热容量对数值计算的一种限制。
From finite difference equation of unsteady-state heat conduction,according to vonNeumann method about scheme stability,the explicit scheme stability condition of two dimension computational heat conduction was given.The stability condition have been analysed with statistico-thermodynamics.and considered the materilal heat capacity is the limit of numerical computational stability.
