Comments
- Sensors can be used to activate airbags, imposed forces, pressures, and fixed velocities.
- Sensors can be used to activate or deactivate these elements: brick, quad, shell, truss, beam, spring or 3N Shell with /ACTIV.
- For sensor type
WORK:
Sensor is activated when work satisfies the criteria:
during Tmin(1) Where,- x
- Distance between node_ID1 and node_ID2
- F(sect_ID)
- Force in the selected section force
- F(rbody_ID)
- Force in the selected rigid body
- F(int_ID)
- Force in the selected contact interface
- F(rwall_ID)
- Force in the selected rigid wall
If sect_ID is 0,
If rbody_ID is 0,
If int_ID is 0,
If rwall_ID is 0,
Work of all forces is calculated in the direction N1-N2, it is always positive.
If node_ID2 is not defined (0), the distance x becomes the displacement of the node_ID1
