Default is 0The assigned global vectors, global namesand information variables can be explicitly used in definition of any export function in a source file.To illustrate how the Stochastic Model data of STRUREL must be used in communication with theC/C++Interface the following well known example will be taken (User Manual: Stone example):The assigned global nameswill have the very same names as in the Stochastic Model: Load, Strength, Diameter, PAR1, PAR2and corresponding values. Eachglobal vectorwill have 5 elements with corresponding values as ordered above.The state functions and user defined functionsfor this example can be expressed in the Symboliclanguage of STRUREL as shown below. // 1. Use vector input in C/C++ source file FLIM(1){Stone: Circular cross section}= FUNC(1)DEFFUNC(1,CPP,CppStone,\_Circular.cpp\// 2. Use global names in C++ source file FLIM(2){Stone: Circular cross section}= FUNC(2)DEFFUNC(2,CPP,CppStone,\_Circular.cpp\// 3. Use explicit arguments in C++ source fileFLIM(3){Stone: Circular cross section}= FUNC(3)(Load,Strength,Diameter,PAR1,PAR2,PI)DEFFUNC(3,CPP,CppStone,\_Circular.cpp\
