KNOWN ISSUES


  • In order to view the generated .tcl file ('Create and view .tcl only' menu option), first associate the .tcl extension with your favorite text editor (e.g. Notepad, Notepad++ etc.).
  • GiD may occasionally crash when spaces are used in new material/element names. Please do not use spaces in names until this issue is resolved in GiD.
  • OpenSees does not combine constraints (multiple 'fix' commands on the same node). As a result:
    • Intersection joints that belong to two lines with different constraints should be handled separately.
    • Intersection lines that belong to two surfaces with different constraints should be handled separately.
  • The horizontal information bar stays in front of GiD material/condition windows when the respective menu options are used; please use the toolbar buttons instead. However, there's no way at the moment to hide the information bar behind the GiD Layer and Copy windows.
