研究三维扩散方程的数值模拟.在非正规六面体网格上,使用积分内插法建立扩散方程差分格式,涉及到27个相邻网格,适用于大变形网格上带间断系数的拟线性扩散方程的计算.叙述差分格式的建立,推导通量流和网格顶点温度的计算公式,给出了数值试验结果.
Numerical simulation for three\|dimensional diffusion equation is studied. Using integral interpolation method, the difference scheme on the irregular hexahedral grid is constructed which consists of 27 neighboring grids and is available for solving quasi\|linear diffusion equation with discontinuous coefficients on distortion mesh. Flow flux through interfaces and temperature on the nodes are deduced and numerical test is given.
