Comments

  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 AND:
    The sensor is activated one cycle after activation at the same time as sensor sens_ID1 and sens_ID2.

  4. For Sensor type OR:
    The sensor is activated one cycle after the activation of sensor sens_ID1 or after the activation of sens_ID2.
