Sensor: about
Introduction
Within the frame of a transient and/or parametric analysis, the exploitation of results is carried out over the assembly of the resolution steps (solutions assembly). To carry out this exploitation, it is necessary to introduce « virtual sensors » that will be able to « measure », and/or « calculate » the quantities we are interested in.
Use
A sensor can be used to:
- measure a local quantity such as: the field in a point, the flux through a face, …
- calculate a global quantity such as: the force or the torque over a part, the energy, …
Definition
A sensor associated to a support, and a formula.
- The support can be a point, a line, a surface, a volume or the entire domain
- The formula is either:
- A predefined formula (energy, force, couple, …), or
- A user's formula that can comprise an assembly of local quantities, of functions and of operators.
When to create a sensor?
A sensor can be created at any moment during the description of the project.
| Sensor created | Description |
|---|---|
| before solving |
|
| after solving |

Possible storage
It is possible to store a posteriori the result with current value of the sensor on condition that the sensor be evaluated, by means of the command Create a result with the current value of the sensor*.
The result of the sensor is stored as an entity in the tree of general data in the entity type Result under the root of the Post processing repertory.
