The Start-In Directory The “Start-In Directory” or “Working Directory” is the location from which the HyperWorks Desktop application is launched This directory defines where certain settings files are written by default, and where customization files will be searched  Configuration files (hmmenu.set, hmsettings.tcl, hwsettings.xml, hm.mac, etc.)  History File (command.cmf)  HyperMesh Model Files, FE Data and Geometry Files (User can browse to different directories for opening and saving) The file browser will also use this directory as its default location for browsing for files This can be considered as the "current working directory" This directory can be changed, thereby changing the location where these files are written to or read from This has the benefit of allowing different settings to be stored in different directories to give control over the HyperWorks Desktop environment for different projects or use cases 10 HMD Introduction HyperWorks 13.0 Proprietary Information of Altair Engineering, Inc Appendix B: HyperWorks Collaboration Tools • Automatic metadata extraction • Maintain pedigree • Version history • Compare properties between versions • Compare files between versions Use Cases & Connectors Examples • Examples of Use Cases • Retrieve CAD from PLM System • Retrieve BOMs from PLM System • Publish FE Meshes/Solver Decks to PLM System • Publish CAE Results & Reports to PLM System • Retrieve Material information from Material Database • Examples of Existing Connectors • Siemens Teamcenter • PTC Windchill • Other PLM Vendors … • Material DB (e.g Key To Metals) • Other 3rd Party Enterprise Applications 444 HMD Introduction Proprietary Information of Altair Engineering, Inc HyperWorks 13.0 Appendix B: HyperWorks Collaboration Tools – HyperWorks Assembly Browser • Build FE assembly models • Maintain properties from PDM  FE  PDM • Seamless Integration within HyperWorks Desktop environment • Batch meshing integration HyperWorks 13.0 Proprietary Information of Altair Engineering, Inc HMD Introduction 445 Appendix B: HyperWorks Collaboration Tools 2.1 -
