6我使用的是LS-RUN,用的重启动做爆炸 错误具体如下: E r r o r t e r m i n a t i o n *** Error 41274 (SOL+1274) (processor # 0) cannot allocate dynamic memory Ran out of memory allocating 1888006035 words for ALE memory for distributing fsi rel displ 我修改内存为2000000000words,但是提示我 Requested memory is 150% of physical machine memory Simulation may run very slow. Start job any way? 可我电脑是40G运行内存的,应该够的呀。

3要么就是出现计算时间两万多小时 要么就是一直flush i/o buffer 材料参数应该是没有问题,只放铝基体也是可以算的,但是一旦加上空心陶瓷球的复合材料放在里面,就有问题了

1各位大佬报这个错误是哪方面出问题了呢? *** Error 70241 (OTH+241) Internal error: request to expand memory to a negative value. This is most likely because the problem you are running requires more memory than the single precision version can allocate. Try the double precision version of the program.

2请问一下报错这个是什么情况 Error 10904 (KEY+904) Integer in *KEYWORD or command line overflows the machine limits: 3200 Please try the double precision version
