浮动网格法和ANSYS结合坝体不均匀剖分时的温控计算

Computation of Temperature Controll in Inhomogeneous Dam by the Relocatable Grid Method Combined with ANSYS

由于非均匀剖分在坝体温控计算中是不可避免的,而通常采用的浮动网格法在处理该问题时实现计算编程很困难,文中提出了用大型有限元软件ANSYS和自己编制的有限元计算程序相结合的方法,来处理在坝体不均等网格剖分的情况下坝体的温控计算,实现了在大体积混凝土温控计算中网格浮动法的普遍应用。

It is inevitable to make inhomogeneous meshing on the computation of temperature control in the dam.But it is difficult that the relocatable grid method adopted generally is used to calculate and program secretly when handling inhomogeneous meshing dams.This paper has put forward the method combining large-scale finite elements program software-ANSYS with personally finite element calculation procedure to finish the computation of temperature control at inhomogeneous meshing dam and make the relocatable grid method apply widely on computation of temperature control in mass concrete.
