nastran提示磁盘空间不足
今天用nastran计算一个很大模型的结构模态，在log文件中出现如下NASTRAN OP2NEW=0 $ MSC.Nastran .lcl file

请问一下各位高手，怎么处理这个问题
你的nastran装在D盘，工作目录也在D盘，要确保你的D盘有足够的空间。
你现在的设置是d:/scratch，找到nastran的安装目录，找到conf的文件把scratch的目录改到盘符大的盘，用nastran直接调用你的文件计算试试 回复 2 # 唯有时光 的帖子
空间足够大，conf文件中memory=estimate，软件估计的存储空间不够

我想请教一下memory应该怎么改才好？ 回复 3 # gb102700 的帖子
这个问题我还没遇到过，应该是你的模型太大
如果网格可以精简的话可以考虑进行精简；nastran计算时的内存调用应该是动态的，是根据问题的规模自适应选择的，建议不要改变该参数，而且你的Requested size已经2047Mb了，这个大小已经跟你的物理可用内存2055 MB接近，已经没有再扩大的空间了。
