Description of the IM

The intensity measure is described as follows:

The inputs are the velocity waveform with units of m/s, and the output is the Specific Energy Density (SED) with units of m^2/s.

Initial verification

A test was conducted using a synthetic waveform, and an external source calculating the expected result separately.

The expected results from a sine wave over the period 2pi

The returned value from running this with noted parameters:


Number of timesteps: 10000

Domain calculation performed over: 0-6.28 seconds

Waveform function used: sin(t)

Intensity measure value: 3.1415926534657683

Testing against SeismoSignal Results

SeismoSignal results are to 5 decimal places.
