FORCE SOURCE

force_dc: generates a constant force at all time.
force_ac: generates a force with AC amplitude, often used for ac analysis.
force_sin: generates a force with sine wave amplitude, with specified frequency.
force_pulse: generates a pulse force, often used for transient analysis.

SYMBOL
REQUIRED PROPERTIES	force_dc: dc_value force_ac: ac_mag force_sin: amplitude, frequency force_pulse:pulse_width, pulse_period, pulse_high, pulse_low, tdelay, trise, tfall
DESIGN TIPS	values for amplitude end with the letter "u" denoting micron-Newton, values for time end with letter "u" denoting micron-second.

POSITION SOURCE

pos_dc: generates a constant position displacement at all time.
pos_ac: generates a position movement with AC amplitude, often used for ac analysis.
pos_sin: generates a position movement with sine wave amplitude, with specified frequency.
pos_pulse: generates a pulse position movement, often used for transient analysis

SYMBOL
REQUIRED PROPERTIES	pos_dc: dc_value pos_ac: ac_mag pos_sin: amplitude, frequency pos_pulse:pulse_width, pulse_period, pulse_high, pulse_low, tdelay, trise, tfall
DESIGN TIPS	values for amplitude end with the letter "u" denoting micron-meter, values for time end with letter "u" denoting micron-second.

ANGULAR SOURCE

ang_dc: generates a constant angular displacement at all time.
ang_cos: generates a angular movement with cosine wave amplitude with specified frequency.

SYMBOL
REQUIRED PROPERTIES	ang_dc: dc_value ang_cos: amplitude, frequency
DESIGN TIPS	values for amplitude denoting degree, values for frequency denoting Hz, can be written as 3k or 1M.
