Applies Butterworth filter on the given dataset at the given cutoff frequency and returns the result as a new dataset. This is comparable to the Butterworth filter provided by LSPrePost. An InvalidOperationException is thrown if the inputs are incorrect. Invalid inputs comprise of an invalid dataset or a cutoff frequency out of valid range (negative or exceeding the maximum cutoff frequency possible for that dataset. The Maximum Cutoff Frequency for a particular dataset can be queried using the GetMaximumCutoffFrequency method in the Ansys.Mechanical.DataModel.Utilities.Dataset.Helpers namespace).
