COSMOSXpress generates a file named partname-COSMOSXpressStudy.CWR in the results location folder to save analysis results. Materials, restraints, and loads are saved in the part document.
If you open a document for which you have used COSMOSXpress and you cannot resume the previous analysis session, click Options in the Welcome screen and set the Results location to the folder where the associated CWR file resides.
When using File, Save As to save the part file as an eDrawing file, you can include analysis results. To do so, you need to save analysis results as eDrawing files in the same folder where the part file resides and then use File, Save As to save the part in the eDrawings format.
