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 short
increase 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！
