提出了一种扩大凝固模拟网格单元数的方法——读写虚拟盘法，并介绍了其工作原理及实现方法．在微机ＤＯＳ系统下，采用该方法对６１０５曲轴这样复杂形状铸件的凝固过程（网格数为１０３７７３６）进行了模拟
A method to expand the number of units of solidification simulation grid was proposed - read and write virtual disk method and introduced its working principle and implementation method. In the computer DOS system, this method was used to simulate the solidification process of 6105 crankshaft with complex shape casting (number of grid is 1037736)
