A forcing function is required to run a model. For our model we'll add a time forcing function. Later, when adding our loads (which in our model will represent electrodes) we'll associate one of these loads with this function.
The time function is generally a short pulse that allows the system response to be extracted from a device or that can be used to analyse reflections from target. We provide a variety of time functions and you can also define your own.
Note: OnScale is based in the time domain. We work with analog signals (waveforms varying over time) that directly correlate with real-world signals. This lets you recreate experimental setups directly in the software to get like-for-like datasets out.
Adding the Ricker Wavelet Function
Follow these steps:
- In the Model Tree, expand Forcing Functions.
- Beside Time, click
. The Define Input Drive Function window shows. -
In the dropdown, select Ricker Wavelet.
- Click Insert.
Our time forcing function is added to the Model Tree.
Note: For the record, here's how the Ricker Wavelet input function looks in the frequency domain.
What Next?
Next let's add the parameters we'll need.
