Using the Adams/View Function Builder 125 Using the Adams/View Function Builder The Adams/View Function Builder is a versatile tool inside of Adams/View, part of the Adams 2013® suite of software, that lets you write expressions, functions, and subroutines to define forces, measures, and motion in Adams products. You can create and modify functions and parameterize values for various entities. This section provides references and procedures for writing expressions, functions, and subroutines using the Function Builder in Adams/View.

126 Adams/View Function Builder Learning Function Builder Basics Learning Function Builder Basics You use two major types of functions in the Function Builder: design-time and run-time functions. Depending on the type of function you want to use, you can work either in the expression mode or the run-time mode of the Function Builder. • Types of Functions • Function Builder Modes Types of Functions The following two sections provide details about the two major types of functions you can use in the Function Builder: • Design-Time Functions • Run-Time Functions Design-Time Functions Design-time functions allow you to parametrically configure your model for optimization and sensitivity studies. Adams/View evaluates design-time functions only during the design process, and not during a simulation, except for optimization and design studies. The Function Builder gives you access to over two hundred design-time functions. In addition, you can create your own user-written functions. The Function Builder categorizes all system-supplied functions based on their functionality. The following table lists the design-time functions categories: Design-Time Function Categories Category: Math Functions Location/Orientation Functions Modeling Functions Matrix/Array Functions String Functions Database Functions Miscellaneous Functions Besides the categories listed above, the Function Builder includes a category called All Functions that lists all design-time functions in alphabetical order. For more information and examples for each design-time function, see Design-Time Function Descriptions.

Using the Adams/View Function Builder Learning Function Builder Basics 127 Run-Time Functions Run-time functions allow you to specify mathematical relationships between simulation states that directly define the behavior of your model. Adams updates the run-time functions only during a simulation. The Function Builder gives you access to over one hundred run-time functions, that it categorizes based on their functionality. The following table lists the run-time functions categories: Run-Time Function Categories Category: Displacement Functions Velocity Functions Acceleration Functions Contact Functions Spline Functions Force in Object Functions Resultant Force Functions Math Functions Data Element Access User-Written Subroutine Invocation Constants & Variables Besides the categories listed above, the Function Builder includes a category named All Functions. This category contains all the run-time functions, grouped by functionality. For more information and examples for each run-time function, see Run-Time Function Descriptions. Function Builder Modes The Function Builder has two different modes: expression mode and run-time mode. Adams/View gives you access to the appropriate Function Builder mode based on the type of operation you want to perform. The following table shows what types of operations you can perform in each mode. Operations and Function Builder Mode For this operation: Use this mode: Expression Building Expressions Creating or Modifying Computed Measures Expression

128 Adams/View Function Builder Learning Function Builder Basics For this operation: Building Design-Time Functions Building Run-Time Functions Creating or Modifying Function Measures Use this mode: Expression Run-time Run-time The following two sections introduce you to the Function Builder modes: • Expression Mode • Run-Time Mode Expression Mode In expression mode you can create expressions, which are the basis of all parameterization. Adams updates expressions when it detects that dependencies have been changed. Performing optimization and design studies can affect the dependencies for some expressions. In addition to design-time functions, expressions can include the following elements: • Design variables • Operators • Operands • Database Access For detailed information on expressions and their elements, see Expression Language Reference. To learn more about the expression mode, see Working in Expression Mode. Run-Time Mode When working in run-time mode, the Function Builder allows you to combine run-time functions with a variety of elements to build functions. After you define the functions, Adams/Solver uses them during the simulation process. The following sections introduce you to the run-time function elements. • Design Variables • Numerical Values • Operators Design Variables Design variables are a means of storing data that you can later use and modify. You can use design variables throughout the Adams/View command language. For example, you can define the radius of a cylinder in terms of a design variable:

Using the Adams/View Function Builder Learning Function Builder Basics 129 variable create variable=my_radius real=40 units=lengthgeometry modify shape cylinder &cylinder_name = .model_1.PART_1.CYLINDER_1 &radius = (my_radius) For more information on design variables, see Expression Language Reference. Numerical Values In run-time mode you can use integers and real numbers. Adams doesn't support complex numbers at this time. Operators You can use the standard set of FORTRAN operators in the functions you create in run-time mode. The operators table below lists the operators Adams/View supports in this mode. The table lists the operators by precedence, with grouping being the highest precedence operator. • Different from FORTRAN convention, when in run-time mode, the unary minus operator has precedence over the exponentiation operator, and exponentiation associates from left to right. Operators This operator: ( ) - ** / * + - Has this role: Grouping Unary minus = negation Exponentiation Division Multiplication Addition Subtraction To learn more about the run-time mode, see Working in Run-Time Mode. Accessing the Function Builder You can access the Function Builder in different ways, depending on the operation you are performing. Adams/View displays the Function Builder in either the run-time or expression mode, reflecting the way you accessed it. For an overview of the Function Builder modes, see Learning Function Builder Basics. The following table shows what types of operations you can perform in the expression mode, and how you can access it:

130 Adams/View Function Builder Learning Function Builder Basics Accessing the Expression Mode for Basic Operations To do the following: Access the expression mode from: The Build menu Build expressions Create or modify computed measures The Build menu Build design-time functions Text boxes that accept expressions The following table shows what types of operations you can perform in the run-time mode, and how you can access it: Accessing the Run-Time Mode for Basic Operations To do the following: Access the run-time mode using: Create or modify function measures The Build menu Build run-time functions Text boxes that accept run-time functions The following sections provide step-by-step instructions on accessing the Function Builder modes: • Working in Expression Mode • Working in Run-Time Mode Working in Expression Mode You access the Function Builder in expression mode in several ways, depending on the operation you are performing. The Function Builder might look slightly different depending on the operation for which you intend to use it. For example, if you open the Function Builder to build a custom function, you'll notice that it includes boxes for entering general attributes for functions. For information on design-time functions, functions you can use in expression mode, see Design-Time Function Descriptions. In expression mode you can perform three basic types of operations: • Building Expressions • Creating or Modifying Computed Measures • Building Design-Time Functions Building Expressions You use the expression mode when you want to build expressions to use in various operations. Some of the operations for which you can use expressions include parameterizing values for point and marker

For more information on expressions, see Expression Language Reference. To perform such operations, you can access the expression mode from the pop-up menus of boxes that can be parameterized. To access the expression mode from a box: 1. Right-click any box that accepts expressions, point to Parameterize, and then select Expression Builder. The Function Builder appears in expression mode, as shown next. 2. Build your expression, and then select OK. Adams/View inserts the expression in the box from which you displayed the Function Builder. Creating or Modifying Computed Measures If you want to create or modify computed measures, you use the expression mode of the Function Builder. To create or modify computed measures, access the expression mode from the Build menu, as shown below: To access the expression mode from the Build menu:
