ANSYS計算閃退,電腦16G運(yùn)行內(nèi)存,提示RAM內(nèi)存不足,怎么回事? 已有6人參與

During this session the elapsed time exceeds the CPU time by 4939%. Often this indicates either a lack of physical memory (RAM) required to efficiently handle this simulation or it indicates a particularly slow hard drive configuration. This simulation can be expected to run faster on identical hardware if additional RAM or a faster hard drive configuration is made available. For more details, please see the ANSYS Performance Guide which is part of the ANSYS Help system. |

該信息給出了兩個可能: 1 物理內(nèi)存不足。你的機(jī)器有 16 G 內(nèi)存,但是 ANSYS 未必能使用這么多內(nèi)存,這與你使用的 ANSYS 版本和具體設(shè)置有關(guān)。假如你使用的是 32 位的 ANSYS,ANSYS 最多能使用 2G 的內(nèi)存;如果你用的是 64 位的軟件,才能充分使用 16 G 內(nèi)存。 2 你的硬件本身太慢?赡苁桥渲玫膬(nèi)存或硬盤的質(zhì)量有問題;蛑靼宓慕涌谶x擇不當(dāng)。 具體是什么原因,你可以分析一下,或者請有經(jīng)驗的人幫幫忙。 |

Today I use ANSYS/LS-DYNA to calculate a model. For checking the estimated time to complete, I press Ctrl + C. the main windows close. I see the warring *** WARNING *** CP = 87.312 TIME= 21:25:31 During this session the elapsed time exceeds the CPU time by INFINITY%. Often this indicates either a lack of physical memory (RAM) required to efficiently handle this simulation or it indicates a particularly slow hard drive configuration. This simulation can be expected to run faster on identical hardware if additional RAM or a faster hard drive configuration is made available. For more details, please see the ANSYS Performance Guide which is part of the ANSYS Help system. But I now it is wrong because I calculate this model many times and today, I just make a small change. When I press ctrl it resumed. I guess a lot of time briefly was briefly spent waiting for I/O to complete. You just wait a moment. It will be ok. |
