As a CubeSat specification requirement, the satellite must have its 1st resonant frequency above 100 Hz.  Most major forcing amplitudes in launch vehicles occur below 100Hz.  The goal is to design a satellite which will not be destroyed by some forcing near or at a resonant frequency during the launch phase.

Under the Modal tab in the Outline window, left click Analysis Settings.  Set the Max Modes to Find to 5.  Select Limit Search to Range and click* Yes.  Leave *Range Minimum at 0 Hz and set Range Maximum to 1000 Hz.  These settings allow us to reduce run time by using some foresight as to what modal frequencies we expect to see and care about.
