One thing I learned today - Starting from HyperWorks 11, all the help is maintained on the HyperWorks website.. That's convenient for me since I always have access to internet at work and I can just go to the web to get the latest and greatest documentation.
Here's the MotionView/MotionSolve help - http://www.altairhyperworks.com/hwhelp/Altair/hw11.0/help/mbdsol/mbdsol.aspx
I think you may have to login to the Client Center to access this, but not sure.
Enjoy,
Dynamic Guy
