  1. Sensors can be used to activate airbags, imposed forces, pressures, and fixed velocities.
  2. Sensors can be used to activate or deactivate these elements: brick, quad, shell, truss, beam, spring or 3N Shell with /ACTIV.
  3. For Sensor type GAUGE:
    • Sensor is activated (at Tstart) if one of the gauges gives a presure greater than Pmin during a time greater than Tmin.

      Tsensor = Tdelay + Tstart

    • Tstart is the time when pressure criteria is reached.
