|
|
|
Load functions and response functions can provide sensors.
Pressure, velocity, displacements, acceleration, stress,…
Frequency Domain
Time Domain
- 1 E.g. the force during a bump event of a car from Motion
- 2 Local stresses in a component
RMS Value in specified frequency band
Min and Max values in specified frequency band

|
|
Vector based results (e.g. acoustic pressure on the field points) can be converted into Load or Response functions which then can provide sensors |
| |
|
|
From Motion expressions, sensors can be created. |
