增加２G内存后怎么还是内存不足？
以前发过此问题，ANSYS LS-DyNA下，solid168建立钢管的模型，网格划分约20000个单元，计算高频的压力载荷作用于钢管的端面，钢管中部有一小圆孔 直径6mm，自由边界条件，求解每次都是约30秒就退出，messag提示内存不足（原来是１G),我增加了２G内存条（威刚的 ，ANSYS运行内存我设置为３２００MB，运行后，messag还是提示内存不足，我把１G拔了，再运行还是同样的提示，Error Memory is set 1532637 words shortincrease the memory size.
Current memory size 8500000有时还打不开原来建的模型。这是为何？请高手指点，谢谢！

E r r o r t e r m i n a t i o n ANSYS在windows32的系统下只一般实际调用不了那么多内存的，一般只能用到1500MB，再增加物理内存没用的，操作系统就限制死了的
一般解决上面问题有两个：1、用windows64位的（当然CPU要支持64位的）；
2、在linux 或unix等系统下运行ANSYS,那样有多少物理内存，都可以用到。

ANSYS在windows32的系统下只一般实际调用不了那么多内存的，一般只能用到1500MB~~~~~~~~~~~~~
11.0能用到1.8G了，呵呵
另外，还可以增加虚拟内存，利用页面文件解决大模型。 谢谢！我试试看。
