重新stop一下license，再运行，检查你的系统时间，是否与软件一致。nastran是1966年美国国家航空航天局(NASA)为了满足当时航空航天工业对结构分析的迫切需求主持开发大型应用有限元程序。MSC，NASTRAN能有效地求解大模型，其稀疏矩阵算法速度快而且占用磁盘空间少，内节，点自动排序以减小半带宽，再启动能利用...
在SC3D中对几何的纠错和兼容能力可以说是同类软件中的佼佼者,并且具备自动修复不合格网格的功能。如果在启动自动修复网格命令的情况下还出现了编号9031的错误,说明几何出现了畸形情况,此时需要返回几何模型进行排查并做相应的修复。 可以调节设置模型清理选项的公差大小来过滤极小特征。合理的是小特征公差范围在5-10之间...

前段时间无意中看到了MSC.NASTRAN动力学分析培训的推广,甚是兴奋,于是,老黄和段博士两人就跟老板申请了点出差补助(中国好老板),背着笔记本,于2016.5.18日踏上了前往帝都之路。 这次培训最大的收获就是认识了NASTRAN高级工程师李老师、系统的学习了动力学分析内容(...
