Step 1. Opening ansys workbench
• Overview:– Start > ANSYS Workbench– Create Static Structural analysis system

[Optional] Note on save as …
• Do not save to a network drive location– //server/share/folder/file.wbpj
• Instead used a local drive or mapped network drive: browse computer, for example– U:/folder/file.wbpj
• Reason: when solver tries to start, it will fail if a file it needs is in a network drive location (even if there is an equivalent mapped location). Can save and re-open from the mapped location. To view where your files are,– Workbench menu > View > Files
