登錄如圖memory設(shè)置為2048000000,應(yīng)該調(diào)用約8G內(nèi)存但實(shí)際只使用了900M內(nèi)存還望LS-DYNA高手解惑
LS-DYNA并行求解的時(shí)候是不是核數(shù)越多計(jì)算的越快啊?該怎么設(shè)置?有的時(shí)候用AMD的cpu求解的時(shí)候總是報(bào)分配內(nèi)存錯(cuò)誤是什么原因啊?有沒(méi)有大佬遇到過(guò),求指導(dǎo)!!!?

前一次運(yùn)算采用mpp40核計(jì)算,小型重啟動(dòng)時(shí)仍然用40核,但是總是不斷生成disk文件然后報(bào)錯(cuò),報(bào)錯(cuò)信息為forrtl:severe(174):SIGSEGV,segmentation fault occurred;

*** Error 70023 (OTH+23) LS-DYNA failed to allocate 50000000000 words of memory.
求指教

2.單元過(guò)多,所需要的內(nèi)存過(guò)大(但為什么不提示呢)。我單獨(dú)只設(shè)置一堆炸藥讓他們自己炸開(kāi)是可以計(jì)算的。
