Introduction

The function 2D utility defines an arbitrary function of two variables, F = F(x, y), where x and y are the independent variables and F the value of the function. The functions can be represented in four mutually exclusive manners.

  1. If keyword @TABULATED_FUNCTION_2D_NAME appears, the function is represented as a tabulated function, TbFun2Name. This approach is the simplest is the function is defined by experimental measurements.

NOTES

  1. Various types of functions can be defined to be used by various objects of the model. The list of allowable function types is given below.
  2. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
