MotionView allows you to save the solver input deck and invoke the solver in one step.  To do this, a script (or .bat file on PC) must be registered in the preferences.mvw file so that it can be used when you select Run from the Run Solver panel.  Use the *RegisterSolverScript() preference statement to register the solver script.  When registered, the scripts can be selected from the Run Solver panel.  For ADAMS and SIMPACK, the MotionView installation contains scripts that require you to edit them only once before using.  These can be found in the <ALTAIR_HOME>\utility\mbd\launch_scripts\ directory.
