Use the Parameters Browser to parameterize the contents of a session file or report template and automate a variety of analysis processes with
the Parameters Browser.
Explore, organize and manage your personal data, collaborate in teams, and connect to other data sources, such as
corporate PLM systems to access CAD data or publish simulation data.
Overview of external readers and the Altair Binary Format, the generic ASCII reader, running HyperWorks in batch mode, using Tcl/Tk commands, translators, and result math.
Polyfit plus batch digital filter. batchpolyfit fits a polynomial to the data and subtracts that polynomial from the data, leaving only the residuals. It
batch filters the residuals, then adds the polynomial back in.
Returns the cumulative probability that a real-valued random variable x with a given continuous distribution will
be found to have a value less than or equal to x.
Creates a new x vector from the x vectors of multiple curves in the range between the maximum of all minima and the
minimum of all maxima. All curves must have an overlapping x range. The returned vector contains only the points of
the vector which has the most points in this range.
Magnitude of a Fast Fourier Transform (FFT) function. FFTMag performs a frequency analysis on a single curve's data
and produces an output that indicates the magnitude of the frequency content of the input file.
For a given set of x values, returns a vector of values that smoothly transitions from (or steps from) one level of
y value to another. This function can create a vector that has many steps and can use different forms of interpolating
step functions.
The OLC function is able to calculate both the Occupant Load Criteria (OLC) and OLC++. OLC++ combines OLC with the
time of maximum deformation (Tv=0) and the sliding mean integral over a window of 25 ms (SM25), as shown in the formulas
below.
Returns a vector or matrix of values based on the channel name (string), not on the index. Indices will only be used
for specifying the range of the returned vector.
The relative displacement (reldisp) math function allows you to transform vector results from time history or animation result files according to a
coordinate system defined by three nodes from the same result file.
Takes a vector and returns a vector containing the indices of the points from the input vector, which are non-duplicate
points (for successive points).
Sliding mean integral filter. Smooths the curve by moving a sliding window over the curve and calculating the mean
value. This is done by calculating the area of the sliding window regardless of whether or not there are points at
the window boundary, and divides this area by the window size.
