关于没有xdb文件生成
浏览：143069 回答：2
在patran中调用nastran进行分析之后，没有xdb文件生成。直接打开nastran，对.db文件分析之后，依然没有xdb文件生成。有没有哪位知道是怎么回事打开生成的f06文件之后，发现有这样三条语句：
*** SYSTEM FATAL MESSAGE 228 (SCA.MDSolver.Io.AccessAccess.AccessAccess::setScratchDirectory)
The directory f:/ does not exist.
*** USER WARNING MESSAGE 209 (SCA.MDSolver.Io.AccessAccess.AccessAccess::isEchoSortRequested)
