About Run-Time Functions

Run-time functions allow you to specify mathematical relationships between the simulation states that directly define the behavior of the system.

During the run time of your simulation, many system states change: time elapses linearly, parts displace, and applied forces change in a variety of ways (such as, sinusoidal, and non-linear). Adams View allows you to manipulate the states of these system variables with run-time functions. Using run-time functions you can build dependencies, such as a motion that's a function of (TIME)2 or a force that's a function of velocity vertical displacement.

You can work with run-time functions from boxes that expect run-time functions, most commonly found when working with applied forces and generated motions. You build a run-time function in the Function Builder and then insert the function in the box that accepts run-time functions. To learn how to use the Function Builder to work with run-time functions, please refer to the first three chapters of this guide.

When you enter in the Function Builder a function longer than 80 characters per line, Adams View alerts you that your function is too long. If your function is longer than 80 characters per line, it is best to split it into two or more lines.
