Different HyperWorks applications have different methods for launching the Tk Console (tkcon), also called the command window.  For Altair Simulation products, use Tools > Command Window….  For HyperMesh, click View > Command Window.

Once tkcon is open, Tcl/Tk commands, as well as application specific Tcl API commands, can be entered directly.

Tcl scripts can also be launched from within tkcon.  The source command is used for this purpose:

 

cd "C:/My_Tcl_Scripts"

source hello.tcl
