When working with Tcl scripts in HyperMesh, it is often useful to get the name of the currently opened model file. For example, you may want to automatically create output files, reports, or logs using the same name as the active HyperMesh model.<\/p>\n
HyperMesh provides the command Complete Example:<\/p>\n This approach is useful when you want to write scripts that automatically save results or export files into the same folder as the active HyperMesh model.
