See also the QPROP web page.
QPROP/QMIL are alternative programs, which are more geared for doing parameter sweeps and coupling to motors or generators.

Software

Note: The source code for XROTOR itself is the same for Unix and Win32. The plot library directory (plotlib) has a separate win32 subdirectory. See all the README files for more info. Win32 Notes: Interaction with Win32 XROTOR is through a DOS-type text console window. Some of Microsoft's Win32 OS'es (Win95/98/ME) have limitations on # of lines in a console window and cannot fully display XROTOR menus or output. Win95/98/ME also have other shortcomings with regard to resource usage and stability although XROTOR runs under these OS'es. Windows NT, Win2000 and Windows XP are the recommended Win32 platforms.
